qgrid does not appear about qgrid HOT 17 CLOSED

I had the same problem when working with anaconda (after conda install qgrid). Finally I succeeded to get it working in anaconda as follows:

• I moved the folders created by qgrid.nbinstall to the anaconda folder ... \share\jupyter\nbextensions
• I had to conda install ipywidgets
  After this the qgrid appeared. I tried to look into the qgrid.nbinstall function, but at first glance it was not clear to me what should be changed.

Same problem here - the problem was resolved by reloading the notebook - not sure what the issue was

from qgrid.

I don't know what those errors mean, but I would suggest looking at the sample notebook on nbviewer to see how qgrid is used. Two things that I see missing:

1. You need to run nb_install to install the widget to your local jupyter notebook instance
2. You need to call show_grid to actually render the DataFrame. Qgrid doesn't automatically take over DataFrame rendering, it has to be told explicitly via a call to show_grid.

To get the sample notebook running locally, clone the repository using
git clone https://github.com/quantopian/qgrid.git
and then follow the steps in the section Running the Demo Locally. Apologies if the docs are confusing, I'm going to try to clean them up a bit.

Ooops I think I copied the wrong python code. How silly of me. This is the code I am using:

import qgrid

qgrid.nbinstall(overwrite=True)  # copies javascript dependencies to your /nbextensions folder
qgrid.set_defaults(remote_js=True)
import pandas as pd
import numpy as np
randn = np.random.randn

# Set this pandas option to prevent the grid from being too big
pd.set_option('display.max_rows', 8)

# Get a pandas DataFrame containing the daily prices for the S&P 500 from 1/1/2011 - 1/1/2014
from pandas.io.data import get_data_yahoo
spy = get_data_yahoo(
    symbols='SPY',  
    start=pd.Timestamp('2011-01-01'),  
    end=pd.Timestamp('2014-01-01'),
    adjust_price=True,
)
qgrid.show_grid(spy)

from qgrid.

Where specifically is nbinstall supposed to copy the extension to?

from qgrid.

Your code worked for me. What version of qgrid / pandas are you using?

from qgrid.

So, I no longer use the machine I had this issue on. I tried it on my new machine, (also with safari instead of chrome) and worked fine.
If I run into trouble again, I will update, but for now I will close this issue.

from qgrid.

Unfortunately I have the same issue and used exactly the instructions from the example notebook. Is there a way to debug this? And what information would you need? Browser, packages, etc?

Edit: I think copying the data to my local folder does not work, because I can't find any files there. After calling qgrid.nbinstall with user=False (from the console with admin rights), files get copied to /usr/local/share/jupyter/nbextensions/qgridjs. Still, no qgrids are shown in my notebooks.

Edit2: Heres the output from my browser console:

I had trouble finding the qgrid extension location.

It's located in ~/.local if you did pip install --user qgrid

Copying the files like @keluc noted fixed this issue for me (I'm also using anaconda):

 cp -r ~/.local/share/jupyter/nbextensions/qgridjs/ ~/anaconda3/share/jupyter/nbextensions/

Thanks!

In case anyone is still seeing this issue, please try installing the new qgrid 1.0 beta using the instructions here: https://github.com/quantopian/qgrid#installation. As you'll see in those instructions, the nbinstall step that appears to be an issue for some people is no longer required. This is because qgrid 1.0 follows the recommended installation/deployment guidelines provided by the ipywidgets team.

Only caveat for using qgrid 1.0 is that you need to be using ipywidgets version 7.x or newer.

I have qgrid installed via conda install qgrid but in the notebook, I get no response with;
import qgrid
qgrid.show_grid(df)
are there other steps that I need to take beyond importing it?
There are no errors when the cell is executed. My details are:

Operating System: Mac OS High Sierra
Browser: Firefox
Python Version: Python 3.6.3
How did you install Qgrid: conda
Notebook version: 5.0.0
ipywidgets version: 7.1.2
qgrid version: 1.0.1

from qgrid.

Upgrading to the latest browser may solve the issue.

from qgrid.

I tried to get it going on a simple sample but no luck so far...

I used pip for installation on python3. qgrid==1.0.2
chrome: Version 62.0.3202.94 (Official Build) (64-bit)
running on uptodate arch linux... (hope qgrid is not Windows only)

from qgrid.

@markfink : Hey i am having the same problem with exaclty the same code but I am using Windows version. Were you able to rectify the same.

from qgrid.

All, I have had some challenges on WinPy 3.6.7 / newer Chome / Notebook / fresh install of qgrid and samples today, but it's partly functional. I don't see any toolbars.

Two suggestions for users:

1. My dfs only show up after qgrid_widget.get_changed_df(), not before. This only works in a second cell after the cell where show_grid runs.
2. See if your notebook says "Untrusted" on the top right or if you have any messages like the one below in your cli:

[W 09:03:28.306 LabApp] Notebook winpyfolder/folder/mynotebook.ipynb is not trusted

If you do and only if you trust the notebook author, click trust on the top right of the notebook. Specifically you may need to click untrusted and then trust.

from qgrid.

@brettbrocato to see the df's, be sure you're saving the widget to a variable, and then calling that variable so it's shown in the output cell; this got my for the longest time.

import qgrid
qgrid_widget = qgrid.show_grid(df)
qgrid_widget # omitting this line saves the widget to a variable but it won't show

Apologies if you already knew this - just thought I'd place this here for anyone new to qgrid who stumbles across this!

I'm am experiencing the same problem as the OP: web app works in jupyter notebooks (local), it works in Voila (local), but when I run it with Heroku - it doesn't display the jupyter notebook displays.

it seems to be having trouble with "GET /voila/qgrid.js" and "GET /voila/bqplot.js"

Could this be a related issue?
