problem of running in jupyter notebook #18

Closed kkhuang1990 closed 7 years ago

kkhuang1990 commented 7 years ago

I followed the instructions as you wrote on the github and can successfully run the test codes. however, I met the following error when running in my jupyter notebook

OSError Traceback (most recent call last)

in () 16 target = [5, 3, 1, 4, 5, 1, 5] 17 ---> 18 fm = pywFM.FM(task='regression', num_iter=5) 19 20 # split features and target for train/test /usr/local/lib/python2.7/dist-packages/pywFM/__init__.pyc in __init__(self, task, num_iter, init_stdev, k0, k1, k2, learning_method, learn_rate, r0_regularization, r1_regularization, r2_regularization, rlog, verbose, seed, silent, temp_path) OSError: `LIBFM_PATH` is not set. Please install libFM and set the path variable (https://github.com/jfloff/pywFM#installing). actually I have already set the LIBFM_PATH in my ~/.bashrc file as this: export LIBFM_PATH=$HOME/local/libfm/bin I don't know why the jupyter notebook cannot find this path

Hello,

I had a previous issue regarding this (#11), and it seems Jupyter-specific problem: https://github.com/jupyterhub/jupyterhub/issues/330

As some hints, you can either try exporting into .profile, or you could also set it directly using Jupyter instructions: http://ipython.readthedocs.io/en/stable/interactive/magics.html#magic-env

When you find a solution, please report back! 👍

thanks, after restarting the jupyter notebook, it works for me

Did you change anything? Or just a simple reload of jupyter worked? I'm assuming with the reload it started loading the new set of env variables that were on the bashrc (similar to when it happens to consoles that are open while you change .bashrc). Was that it?

kkhuang1990 commented 7 years ago

Actually I have made two modifications. (1) add this line to ~/.bash_profile.(the path should he the directory where you installed your libfm into) export LIBFM_PATH=$HOME/local/libfm/bin (2) add the following settings to ~/.jupyter/jupyter_notebook_config.py for var in os.environ: c.Spawner.env_keep.append(var) It may also work if you only append the LIBFM_PATH to env_keep. I am not sure. For completeness, I add all path variables

Then I restart the jupyter, It works

Thank you for the feedback! Soon I'll update the README with a link to this issue for future reference. :)

Traceback (most recent call last): File "factorization_machine.py", line 18, in fm = pywFM.FM(task='regression', num_iter=5) File "/anaconda2/lib/python2.7/site-packages/pywFM/init.py", line 122, in init raise OSError("libFM is not checked out to the correct commit." OSError: libFM is not checked out to the correct commit.(https://github.com/jfloff/pywFM#installing).

When I tried to run the demo code, I met above errors.

Did you follow all the steps from https://github.com/jfloff/pywFM#installing ?

I didn't find jupyter_notebook_config.py but found a empty file named jupyter_notebook_config.json. Is it a file created by yourself？
