Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe:

• License is not an SPDX identifier (or a custom LicenseRef) nor an SPDX license expression.

Documentation on acceptable licenses can be found here.

Thanks @martinRenou. Looks like checks are failing.

Yes, I guess we need to make a jupyterlab_widgets rc first

Conda is not able to resolve the environment if we include Python 3.10 (while mamba is able to do it)

[jtpio]

Thanks!

We can look into the Python 3.10 issue when solving the environment in a separate PR.

Opened #72 as a follow-up.
