kxsystems / jupyterq Goto Github PK

VSCode is well-suited to run Juptyter python notebooks and can do so with different (conda-) environments. However, jupyterQ won't launch on my computer even though it shows an option to select "Q(kdb+)" kernel (the option became available after installing jupyterq). There isn't a dettailed error message I could find, it just shows:
"Command 'Jupyter: Select a Kernel' resulted in an error (Timed out waiting to get a heartbeat from kernel process.)"

Hi,
I appreciate your help with this issue, there is a problem with non-existing file on repo https://conda.anaconda.org/kx/win-64/current_repodata.json.

Hi,

When I start the jupyter notebook, and create a new jupyter notebook file, and put kernel as kdb+, it indicates that it cannot connect to it. I have already started q server running locally on my pc. Both q and jupyter running under same disk and conda environment. under. Window10

External Query

I have a table in kdb – just 5 columns and 100 rows – all numeric (features of a model let’s say)

I want to display the contents of this table in jupyterq from seaborn.

Specifically I want to:

1. display the distribution of the 2nd column using the sns.displot function.

sns.displot(table, x=”feature2”)

in python

2. display two comparative columns together – ie:

sns.displot(table, x="feature2", hue="feature3", stat="density")

3. finally I want to display the relationships of all features against each other, perhaps with

sns.pairplot(table, diag_kind=’kde’)

Currently this behaviour is not supported likely due to the function used to provide inline displays in kxpy/kx_backend_inline.py, more research is needed on this however

Using this:
jupyter console --kernel=qpk

I get this stack trace..

Dear authors,
I am studying jupyterq. I try to run docker image but get the license error: licence error: k4.lic. I have a personal licence kc.lic but I don't know how to let jupyter find my licence file. I can enter q session by typing q in the terminal, so the environment in my macOS should be fine. Can you help to figure out the issue? Thanks.

IPython.display error raised:

The above code should return a PNG image but returns nothing.

Actively attempting to display the plot using IPythons display function returns the following

Hello,

I'm getting "RuntimeError: Kernel didn't respond to kernel_info_request" when running "jupyter console --kernel=qpk" even though I followed the instructions for installing embedPy and JupyterQ exactly. I thought that I can avoid doing this by changing my default kernel to qpk, so I went ahead and tried to just launch a .ipynb, which returns 404s that I think are caused by jupyterq_licensemgr not being found. Any help would be appreciated. Below are more details:

I was following #49 but it has since been closed, so I decided to open a new issue. This is where my problem deviates:

In the original thread, @cmccarthy1 suggested:

1. it may be a conflict with PyQ ----> I do not have PyQ installed, so this shouldnt be the issue
2. to confirm that embedPy and JupyterQ were installed exactly like the instructions ----> I did this too using the "Download and install a release" path for both
3. to confirm that this is being done in an environment ----> I think that I'm doing this as indicated by the (jupyterqenv) at the start of my commands.

I thought that I can avoid having to launch the console with --kernel=qpk if I just edit my jupyter_notebook_config.py to change my default to qpk, which I have verified when launching jupyter notebooks kdb+Notebooks.ipynb, because the top right shows Q(kdb+)
My jupyter_notebook_config.py:

## The name of the default kernel to start
#  Default: 'qpk'
# c.MultiKernelManager.default_kernel_name = 'qpk'

This is what I get when running jupyter notebooks kdb+Notebooks.ipynb, even though I see that jupyterq_licensemgr is untouched

Hi all,

when starting the jupyterq kernel we can see that the jupyterq_server.q q process is trying to make a connection to the 'outside'. See the strace below. Our servers are all secured and do not allow any connection to the outside.
However this side effect will timeout in 2 minutes making the q kernel unresponsive. Is it possible to turn this off?

Thanks,
Kim

The following issue was raised by Seth Oldham in K4 Listbox, this issue presented here is to allow for up to date progress to be reported.

I have put together a simple notebook with an interactive Bokeh control using the following code

## /%python 

from ipywidgets import interact
import numpy as np

from bokeh.io import push_notebook, show, output_notebook
from bokeh.plotting import figure
from bokeh.resources import INLINE

x = np.linspace(0, 2*np.pi, 2000)
y = np.sin(x)

p = figure(title="simple line example", plot_height=300, plot_width=600, y_range=(-5,5),
           background_fill_color='#efefef')
r = p.line(x, y, color="#8888cc", line_width=1.5, alpha=0.8)

def update(f, w=1, A=1, phi=0):
    if   f == "sin": func = np.sin
    elif f == "cos": func = np.cos
    r.data_source.data['y'] = A * func(w * x + phi)
    push_notebook()

output_notebook(resources=INLINE)

show(p, notebook_handle=True);
interact(update, f=["sin", "cos"], w=(0,50), A=(1,10), phi=(0, 20, 0.1));

When I run that with the Python kernel, the interactive controls work as expected. But when I switch to the kdb kernel, and uncomment the /%python magic, the plot displays as expected but the controls don't have any effect. The logging from the notebook server does not reveal anything that seems useful, but I am including it here in case I'm missing something

I am trying to install jupyterq into my Linux home directory. I have read only access to QHOME.
Is this something possible to do?

Hi there,
I have been working with jupyterq for a while now. I was trying to use KX/ml library for q, in order to study ml and profound data analytics with q, and I came to realize that I needed insights license in order to use this library.
Now I have my insights license, but when using it corresponding key (kc.lic) in Jupyter notebook, the kernel doesn't load. Instead, if I use my previous key (a regular license, not insights) it works perfectly fine. What can I do in order to solve this?

Kind Regards

I am working on Mac. q works on the terminal but when I lunch it from Jupiter notebook it is not able to connect to the kernel.

here is the error message I get:

Fantastic work on taking advantage of key capabilities of the Jupyter Notebook capability, including autocomplete, syntax coloring, inline help.

One thing that I think would be a big win for users would be to render tables using Jupyter's HTML rendering capability, in the same manner that Pandas dataframes are rendered.

To be clear, the current text-only rendering is entirely familiar to Q users and as such there are no negative surprises for experienced users. This would be a strict enhancement to the JupyterQ experience!

So it seems the kernel can start put embedPy somehow fails. Can't figure out what is the problem here.
Put all jupyterq files plus p.q and p.k into /opt/anaconda3/q and p.so and jupyterq.so into /opt/anaconda3/q/m64.
Added "DYLD_LIBRARY_PATH": "/opt/anaconda3/lib" to kernel.json for qpk kernel. To no avail.

Any help will be appreciated.

Hello,

When doing

print("toto")

in a jupyterq notebook nothing is printed.

When doing the same in a console (after loading p.q) it works.

Is it expected or is it due to something I customized in my setup? It makes debugging embedPy's python code very hard in a notebook.

Thanks,

Amaury

I'm trying to install jupyterq. But it can't run. In jupyter notebook, the kernel dies immediately after I open a new Q notebook and tries to restart but fail.

Then I try the jupyter console with:

$ jupyter console --kernel=qpk

There is no response. So I suspend the process with ctrl + C.
It shows the error message as below:

It seems like an issue with jupyter. But it works pretty well with Python or R kernel. So I believe it is more likely to be an issue here.

Hi, getting below error after I start anaconda navigator. please help

Most of the things I tried with ipywidgets work well, but here I don't understand what's wrong.

/%python
import ipywidgets as widgets
from IPython.display import display

out = widgets.Output()
def foo(x):
    with out:
        print(x)

b = widgets.Button(description='Button')
b.on_click(foo)

display(b)
display(out)

When calling foo('bar') directly it works well : 'bar' is printed in the Output widget.
When pressing the button it doesn't.

Doing exactly the same thing with a python kernel works.

Looks like pykx and jupyterq do not work well together. Is there a way to fix it?

Thanks,
Kim

Any idea's on how to troubleshoot this error?

Issue/feature that I would love to see is the support to connect to the remote instance of Q, something like qcon. In my case I have Q instances running and accumulating data, I connect to them and run some queries and then disconnect when I am done. Using hopen is not as comfortable as just qcon into the instance and using auto completion facilities of the jupyter console.

It looks like JupyterQ doesn't like ":" in python codes:

/%python
d={"a":2, "b":3, "c":4}

the error I get:

parse error
assign

Is there a workaround?

Thank you very much for your help!

Hi,

I installed jupyterq successfully via conda and noticed that it doesn't create kernel.json as part of the installation so I had to manually create that.

While it's an easy step, I think it would be great if that step was automated and users didn't have to worry about creating that file!

Everything else worked smoothly!

Hi,

I am having a similar issue to others regarding not being able to connect to the kernel.

I installed jupyterq on a windows machine using anaconda. I have then created a new environment as I already had a 64 bit version of Kdb on my machine. I activated the environment and attempt to run a jupyter notebook but encounter the following error.

'2019.10.15T10:43:21.616 libpython [6] C:\Users\MYUSERNAME\Anaconda3\envs\jupyterqenv\q\p.q:8: `L`M`H set'@[system"python3 ",;c;{system"python ",c}];if[count M;if[k~key k:`$":",M;L::M]]; .p:(`:./p 2:(`init;2))[L;H]]

From previous closed issues it was asked to provide the versions of the following:

Name--------------------Version----------Build Channel
embedpy----------------1.3.2-------------py37hfa6e2cd_0 kx
ipython------------------7.8.0-------------py37h39e3cac_0
ipython_genutils--------0.2.0-------------py37_0
jupyterq-----------------1.1.7-------------py37hfa6e2cd_0 kx
kdb----------------------3.6---------------2019.08.20 kx
python------------------3.7.4-------------h5263a28_0
python-dateutil---------2.8.0-------------py37_0

When I attempt to run:

$ q p.q

it reports the following:

libpython [2] C:\Users\MYUSERNAME\Anaconda3\envs\jupyterqenv\q\p.q:8: `L`M`H set'@[system"python3 ",;c;{system"python ",c}];if[count M;if[k~key k:`$":",M;L::M]]; .p:(`:./p 2:(`init;2))[L;H]] ^ [0] (<load>) )

Other information which I think is relevant - I previously had a 32 bit version of Kdb installed on my windows machine. I thought this could have been the issue when trying to interface with 64 bit python so I removed all traces of it and reinstalled the 64 bit version using the conda command.

Really appreciate any help in advance.

Thanks!

It is hard too read when the q query is long. Breaking the query down isn't an option either.

Is it possible to add line-wrap to the JupyterQ?

External Request

The following email was received via [email protected] (edited for anonymity)

One of the features I like about running JupyterQ in Jupyter Lab, is the “open console for kernel” functionality. 
This allows you to get a terminal-like input window which looks & feels like a normal KDB session, but with the ability to draw charts etc. 
The main reason this is useful, is when you are diving into a function which you want to run line-by-line for debugging.

In Jupyter Notebook, this is supported when running a Python Kernel by typing a cell magic “%qtconsole”.
This launches a console for the running kernel. I tried this and “/%qtconsole” but neither work. 
Is this feature supported in jupyterq?

Within the current implementation of the Jupyter kernel this is not supported behaviour. Its addition would be welcomed but will need to be technically scoped before any timelines assurances of its addition can be made.

To do:

• Scope out how Python handles the exposure of an interactive python console from the notebook
• Scope out how JupyterLab provides the "open console for kernel" functionality
• Highlight potential issues with providing an option similar to %qtconsole from a JupyterQ jupyter notebook
• Implement or outline the reasoning behind why this will not be a feasible addition

Initial scoping work will dictate if this can be provided as a feature. Timeline on potential addition will be subject to this work.

show `$"\240";

Nothing is displayed if I do this in a notebook, while it works in the console.

The notebook log says

    UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 26: invalid start byte

Is it possible to restrict access to the processes that have opened a port, just like with command-line argument -U password_file.txt ?
(do both the server and the kernel open a port ?)

I just installed the latest miniconda3 for windows 64bit. When I hit the command

conda install -c kx jupyterq
Then it says

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - jupyterq -> python[version='>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

The following specifications were found to be incompatible with your CUDA driver:

  - feature:/win-64::__cuda==9.1=0
  - feature:|@/win-64::__cuda==9.1=0

Your installed CUDA driver is: 9.1

Sounds like jupyterQ is incompatible with python 3.8? Can you update your package in conda?

An issue has been raised where jupyterq_server.q is still running after the jupyter kernel has been properly shut down.

The following fixes were attempted:

1. Adding a timer function to jupyterq_server.q to check if the handle to the kernel was closed and exit the process if so

.z.ts:{if[0~count .z.W;exit 0]};system"t 5000"; 

but the above did not work and the server was still present

2. Adding code to jupyterq_kernel.q, to kill the the server once the kernel is closed

ch.sh.shutdown_request:{[z;s;mc]if[last allowstop;snd[z;s]kr[`shutdown_reply;mc]md[`restart]mc .`content`restart;system"kill ",string neg[srvh]".z.i";exit 0]}

The above addition worked, however hasn’t been fully tested to ensure that it doesn’t cause any side effects that may impact the average user so is not currently being added as a fix

.z.u returns null within Jupyter Notebook using jupyterq kernel

Tried on Linux & Windows, same result on both. As far as I can tell all other .z namespace variables are working fine

Hi,

I am using jupyterq_windows-1.1.11 release and trying to run jupyterq on Python 3.9.7 with KDB 4.0 2021.07.12 on Windows 10 (all 64bit).
I am not using Conda. I was able to run install.bat without errors. I can run q as well. When I run jupyter notebook I see the below errors. What could be the issue?

'2022.03.27T13:57:20.462 libpython

Thanks

Hi

I have set JupyterQ through Anaconda but when I run jupyter console --kernel=qpk I get this error. You know how can I fixt this?

Hi, I successfully installed jupyterQ and KDB kernel, but looks like the ctrl + / shortcut to comment multiple lines doesn't work. Is there any way to configure this feature? Thanks

echo QHOME must be set >2
echo QHOME:$QHOME does not exist >2

is the intent to write files named "2" or echo to stderr?

it would be prudent to check that 'q' exists on the users PATH before trying to execute;
ZO=$(echo "-1 string .z.o;"|q -q)

Upon running install.sh, I get the following -
./install.sh

• jupyter kernelspec install --user --name=qpk ./kernelspec
  [InstallKernelSpec] Removing existing kernelspec in /home/rkkumar/.local/share/jupyter/kernels/qpk
  [InstallKernelSpec] Installed kernelspec qpk in /home/rkkumar/.local/share/jupyter/kernels/qpk
• cp ./jupyterq_b64.q ./jupyterq_help.q ./jupyterq_htmlgen.q ./jupyterq_kernel.q ./jupyterq_pyzmq.q ./jupyterq_server.q './jupyterq*.q_' /home/rkkumar/q
  cp: cannot stat './jupyterq*.q_': No such file or directory
• cp -r ./kxpy /home/rkkumar/q
• cp ./l64/jupyterq.so /home/rkkumar/q/l64
  cp: cannot stat './l64/jupyterq.so': No such file or directory

In order to fix the jupyterq.so not found issue, I have to do the following -
cd build/
vim makefile - change $(SDIR) to the path for jupyterq.c - e.g /home/linuxuser/jupyterq-master/src/c
make
mv l64 ../
cd ../
then run install.sh, which finds jupyterq.so. I can ignore the following, safely -
cp: cannot stat './jupyterq*.q_': No such file or directory

Hello all,
are there instructions on how to set up kdb kerner for jupyter? I followed this page, created a json file, and copy-pasted there the info from:
https://code.kx.com/v2/ml/jupyterq/notebooks/

but I get this error when I open Q notebook in Jupyter:

I checked q and QHOME:

/home/nynfs01/svaury/q/l64/q
-bash-4.2$ echo $QHOME
/home/nynfs01/svaury/q/
-bash-4.2$

I do not use conda on the server.
-bash-4.2$ cat /etc/redhat-release
