Clustergrammer2 0.5.18 not working with jupyterlab 2.0.1

Hi @matrs, I think 0.5.18 did not build the Jupyter Lab extension correctly. I'll let you know when I release 0.5.19. Or you could try 0.5.17, which should work on Jupyter Lab.

The new release of Clustergrammer2 0.5.21 appears to be working in Jupyter Lab 2.0

The change I made was here https://github.com/ismms-himc/clustergrammer2/blob/master/package.json#L48

Based on the recommendation from @jasongrout from gitter.

Let me know if it works for you @LustigePerson @matrs.

[LustigePerson]

Yes, it works. Thanks for the fast fix. It will be in the next FASTGenomics release alongside the new jlab.

[matrs]

Thanks!

Just to clarify, when I try the setup instructions from the readme, it does install 0.5.17 but it doesn't work, that's why I tried other options. For me, 0.5.17/18 works in the lastest jupyter notebook and jupyterlab 1.2.7 which is the last 1.x available in conda . So this setup doesn't work for me:

$ jupyter labextension list
JupyterLab v2.0.1
Known labextensions:
   app dir: /home/mibu/miniconda3/envs/bif/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v2.0.0  enabled  OK
        clustergrammer2 v0.5.17  enabled  OK

@matrs, so you tried pinning the installation version with pip install clustergrammer==0.5.17 and it doesn't work? We'll be releasing a new version probably in the next week that should take care of the Jupyter Lab installation issue. We'll keep you updated.

I think i already tried that but I just did it again to be sure, in a clean environment It doesn't work:

$ conda list | egrep 'cluster|lab|jupyter|notebook'
clustergrammer2           0.5.17                   pypi_0    pypi

notebook                  6.0.3                    py37_0    conda-forge

$ jupyter labextension list
JupyterLab v2.1.0
Known labextensions:
   app dir: /home/mibu/miniconda3/envs/py37/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v2.0.0  enabled  OK
        clustergrammer2 v0.5.17  enabled  OK

Plugin 'jupyter.extensions.clustergrammer2' failed to activate.

It's always the problem with the registry, the thing is that clustergrammer2 0.5.17 and 0.5.18 work with jupyterlab 1.x and the last notebook

Edit: I just noticed that in this try i'm using jupyterlab 2.1 and not 2.0.1, it's because they just released it and it's a fresh installation so conda picked that. Anyways, it's the same problem with 2.1 - 2.0.1 and clustergrammer2 0.5.17 - 0.5.18. Also, when i searched for this problem, i did found errors form other widgets related to jupyterlab 2 and jupyter.extensions.jupyterWidgetRegistry

[cornhundred]

Thanks for checking that again. We'll let you know if we can get it working again in the next release

I just published final versions of the npm packages to work in JupyterLab 2.0.
This message was deleted
@/all - ipywidgets now works in the newly released JupyterLab: jupyter labextension install @jupyter-widgets/jupyterlab-manager
Jason Grout @jasongrout Mar 02 21:02
@/all - For custom widget authors - I anticipate that all you need to do to add JupyterLab 2.0 support is publish a patch release of your npm package, adding || ^3 to your @jupyter-widgets/base dependency versions
For example, your dependency can look like:
"dependencies": {
"@jupyter-widgets/base": "^1 || ^2 || ^3"

Any Updates on this? We are about to Upgrade FASTGenomics to jlab 2.* but the widget seems not to work. I tested 0.5.19 and also 0.5.17-0.5.15 to make sure.

Hi @LustigePerson, I have not had time to try the approach outlined in the previous comment, but I will try it out in the next few days and let you all know. Thanks for your patience on this.
