problem of running in jupyter notebook

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) <ipython-input-24-6bd4815fa3b6> in <module>() 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! 👍

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 …

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？
