ImportError: cannot import name common - don't run in ta-lib dir about ta-lib-python HOT 23 CLOSED

If I remember correctly "make build" in the project dir will fix that issue

Then I had a funny idea.... I was running the python shell in the
checkout dir.
Running the python shell elsewhere let me import talib just fine....

Just posting this in case it helps someone.

Thanks much for the module.

so how do you resolve it??
In my mac, it does report this error.why??

from ta-lib-python.

Hi @no13bus are you getting a traceback similar to the message above? If so, perhaps you have not installed it correctly. You need to have the underlying C library as mentioned in the README, and then complete the installation of this python package by either easy_install TA-Lib (from PyPI) or python setup.py install (from a local git checkout).

from ta-lib-python.

@mrjbq7 yes.First I install cython, then the c-ta-lib, at last your project.But it still have error.

from ta-lib-python.

Hmm, that error indicates it can't import talib.common which is a cython module that is built as part of the installation process. Perhaps there were errors during installation? What OS platform are you trying this from?

My platform is mac os 10.9.5.
in ipython,I type 'import cython', it do not have errors. It is correct.

from ta-lib-python.

this is the result after I type sudo python setup.py install

from ta-lib-python.

Are you trying to run Python inside of the ta-lib hit checkout? Perhaps when you"import talib" it used the talib files inside your checkout instead of the system ones?

from ta-lib-python.

so you mean I run python in the ta-lib source directory??I change another directory, but it does not work.Why?

from ta-lib-python.

If it works from the ta-lib source directory and not from somewhere else, then it means you built it correctly (and that it's working!) but didn't install it to Python's site-packages properly or there is some other configuration issue preventing its use with Python. I wish I could help but it sounds like it would require some more debugging of your local setup.

from ta-lib-python.

my command is sudo python setup.py install
this is the result:

I'm not sure why your system site-packages wouldn't work, if this is the python that comes with OS X, I would expect to see it either:

1. Load from site-packages:

$ cd ~
$ python
Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import talib
>>> talib.__file__
'/Library/Python/2.7/site-packages/TA_Lib-0.4.8-py2.7-macosx-10.9-intel.egg/talib/__init__.pyc'

2. Load from my ta-lib project directory:

$ cd Dev/ta-lib
$ python
Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import talib
>>> talib.__file__
'talib/__init__.pyc'

I'm not sure what might be causing your problem, but somehow it indicates it is copying all the proper files into the proper places, but later somehow its not finding them. Maybe try deleting /Library/Python/2.7/site-packages/talib and /Library/Python/2.7/site-packages/TA_Lib-0.4.8-py2.7.egg-info and then try running make clean and python setup.py install from the ta-lib project directory?

from ta-lib-python.

By any chance, did you upgrade to Yosemite recently? I have seen a similar error importing from the ta-lib project directory, a make clean, make, make test showed the error to go away. Just an idea...

from ta-lib-python.

thanks a lot for your help. I did this: deleting /Library/Python/2.7/site-packages/talib and /Library/Python/2.7/site-packages/TA_Lib-0.4.8-py2.7.egg-info and then try running make clean and python setup.py install from the ta-lib project directory.And it stil have the errors as before. And now my mac osx version is 10.9.5

from ta-lib-python.

thanks very much.It worked.
I type make test,then I get the errors about the numpy errors. Then I uninstall the numpy, and I reinstall numpy, It worked.
ThanksThanksThanksThanksThanksThanksThanksThanksThanksThanksThanksThanksThanks......
You are very nice.

from ta-lib-python.

@no13bus Oh good! Sorry it took so long to get working, I'm not sure what exactly was the problem, but so glad you resolved it! Let me know if you have any feedback as you start using these bindings!

from ta-lib-python.

No,NO. It's my fault.I am not very familiar with the linux command. I should type the make test. Actually I use the macd and other index to analysis the bitcoin trade. I want to achieve the website like this: https://bitcoinwisdom.com/
thanks again. If I come cross some errors, I will report issue for you.

from ta-lib-python.

I tried this and it finally worked for me on my MAC air, running OSX 10.8.5.

sudo pip install cython
sudo pip install numpy

downloaded: ta-lib-0.4.0-src.tar.gz

$ untar and cd
$ ./configure --prefix=/Library
$ make
$ make clean
$ sudo make install
$ brew install ta-lib

notice the prefix to /Library, and then the make clean before make install.

@babalusobral I'm sorry you had problems, I'm not sure what your python situation is, but this is all you should need on a fresh Mac OS X install using the system Python:

$ brew install ta-lib
$ pip install ta-lib

from ta-lib-python.

@mrjbq7 Thanks for your support mate. Definately some screw up on my part. I'm new to MAC and don't know how things work and where things are etc.... probably why i was having difficulties in installing. It works great now. Thumbs up to you man.

from ta-lib-python.

@mrjbq7 Thank for the solution on Yosemite. It worked!!!!

from ta-lib-python.

I did below steps and it worked perfectly well. I was getting error -
cannot import name 'TA_FUNCTION_NAMES'

1. Closed anaconda
2. Went into site packages folder and found talib folders
3. Deleted the folders
4. Opened Anaconda prompt
5. Upgraded numpy - pip install -U numpy --user
6. Installed TA_Lib-0.4.17-cp36-cp36m-win_amd64.whl which I had downloaded using pip install
   This

from ta-lib-python.

Closing all installation issues, if someone has a specific problem please open a new one.
