jupyter-gmaps loaded but cannot be instantiated about gmaps HOT 7 OPEN

i am facing the same issue. Any solution so far?

from gmaps.

I was having this issue for a few days but fixed it by creating a new environment with older versions of the packages I needed, so ylnhari's suspicion that there might be some conflict with package versions seems to be on the money. Since I'm working through a class that wants us to have everything installed with Anaconda my environment isn't super custom, but it worked when I downgraded from the most up-to-date version to anaconda=5.3.0.

For a more general approach my intuition is to target the packages that are specifically referred to in gmaps's requirements.txt (six, ipython>=5.3.0, ipywidgets>=7.0.0, traitlets>=4.3.0, geojson>=2.0.0). I'm afraid I'm far too much of a novice to walk through building only what might be necessary into an environment, so I hope this is enough of a jumping off point for people who want to avoid installing bloat. However if anyone running into this issue wants a quick and dirty solution and isn't too picky about what gets added to the environment, here's what I did:

1. Create new environment with python 3.7.0
2. Activate the environment and install anaconda=5.3.0
3. Install gmaps
4. Since my environment's jupyter kernel wasn't created I used: python -m ipykernel install --user --name myenv --display-name "Python (myenv)"
5. ipywidgets widget extensions were enabled but despite using conda, gmaps's widget wasn't, so I ran: $ jupyter nbextension enable --py --sys-prefix gmaps to load it.

This is just a workaround I think if the current versions of one the gmaps requirements is causing conflicts. I went down a few rabbit holes looking into the errors that get logged to the console and came back with a potential issue with the JS compilier Babel's config. How, where and why that is now getting picked up with updates to python packages is not something I can even guess at let alone attempt to fix, but hopefully this workaround helps for people just looking for things to work!

I fixed this in a development install by updating babel ( https://github.com/babel/babel-upgrade). The issue seems to be that webpack uses babel to transpile the JavaScript so that it works in older browsers. However, the default version, configured in js/.babelrc and described in js/package.json doesn't do this properly for ES6.

@arooj1 , I tried running the same on my other workstation with Linux environment whose environment was untouched and it is working fine there ,now I strongly believe that this is due to some requirements libraries of g-maps that could be creating these issues try @sbenston solution let us know your experience.

Thanks @timcoote .

After spending 7 hours on it, I finally found a way. I made a docker file that solves the problem:

did anybody find here solution to using python3.8 on a virtual environment without conda and without source installation

from gmaps.

@tejalbarnwal it's not possible. You need to use the source installation.
