[Matplotlib-users] Is there any way to get interactive matplotlib in Jupyterlab without conda-forge?

[Jason Grout]

We can see from https://anaconda.org/search?q=ipympl that the Anaconda
channel is not publishing ipympl.

You can install everything in a new environment from conda-forge, which
would avoid the problem of mixing channels. That is what I typically do,
adding a couple of lines to the config file or a couple of command line
switches to the install command.

As you say, publishing this package is an Anaconda issue, totally outside
of our control in developing and publishing JupyterLab. Maybe you could
request Anaconda look into shipping ipympl?

I suppose from your perspective it would be more correct to use the exact
same logic to say that Anaconda's support for JupyterLab is not quite ready
for prime time, given that shipping this package is an Anaconda issue and
not a JupyterLab issue :). (I would not make that statement personally, but
I understand your perspective.)

Thanks,

Jason
