I am facing the problem when I am trying to install the nwbwidgets package, as it gets installed however when I try to import it does says no module.

During installation of nwbwidgets, h5py setup gives an error thus I am unable to import the package

[luiztauffer]

It looks like you’re trying to install in an existing environment. I recommend you try it on a clean environment:

conda create -n myenv python=3.8
conda activate myenv
pip install nwbwidgets

the installation should run successfully before you’re able to import and use it

Yes now the module are working fine, however when I try to run the jupyter notebook in Vscode the kernel died with exit error 1

It shows the following, any idea how to resolve this issue.

Kernel died with exit code 1.

Yes I have resolved the issue and setup the repo locally thanks for help! I have used python 3.9 and used a virtualenv with python-m venv env.

Hi，

how to solve the issue? could you tell me each step?

[bendichter]

@ranningw this error occurred during installation of h5py. I suggest running pip install h5py. If that does not work, you should consult their documentation. If it does work, you should then try pip install nwb-jupyter-widgets.
