Hi! I just pushed a small fix, let me know if that works for you.

[WeiLiPenguin]

Hi, Thank you!

But still not work for me.

I use python2, is that the problem?

I try create new conda env and clone the chemview

cd chemview
pip install -e .
conda install widgetsnbextension
jupyter nbextension enable widgetsnbextension --user --py
jupyter nbextension install --py --symlink chemview --user
jupyter nbextension enable --py  chemview

Best Regards!

I tested the QuickStart.ipynb on Python 2, and it's going ok, does it work for you as well?

Which feature specifically doesn't work?

This problem (nothing being rendered in the notebook) is reproducible for firefox51-linux in a new conda environment with the following packages

jupyter                   1.0.0                    py35_3  
jupyter_client            5.0.0                    py35_0    
jupyter_core              4.3.0                    py35_0 
ipywidgets                6.0.0                    py35_0
widgetsnbextension        2.0.0                    py35_0
chemview                  0.7                      py35_0    gabrielelanaro
chemlab                   1.1                      py35_0    gabrielelanaro

Running demo snippets such as the water molecule balls-and-sticks gives the warning

anaconda3/envs/chemview/lib/python3.5/site-packages/traitlets/traitlets.py:567: FutureWarning: comparison to `None` will result in an elementwise object comparison in the future.

Is it possible to know the traceback from the javascript console? I have some users find out that the browser supported only WebGL version 1 and that was the culprit.

I've just noticed an install error using pip with the extension package:

KeyError: 'The Python module chemview is not a valid nbextension, it is missing the `_jupyter_nbextension_paths()` method

not want to compete with chemview here but just in case you all want an alternative package:
