Witwidget in JupyterLab

Hi there,

I’m experiencing some issues with JupyterLab and WIT visualization.

I have created an Anaconda environment with Python 3.7.3 and JupyterLab v1.0.2. I installed WIT widget as instructed in project’s README https://github.com/tensorflow/tensorboard/tree/master/tensorboard/plugins/interactive_inference#how-do-i-enable-it-for-use-in-a-jupyterlab-or-cloud-ai-platform-notebook and run the demo What_If_Tool_Notebook_Usage.ipynb notebook. Problem is that the output of the last cell is WitWidget(config={'model_type': 'classification', 'label_vocab': ['Under 50K', 'Over 50K'], 'are_sequence_exam… instead of the visualization. I’m using Google Chrome v71.0

In my browser’s console I get the following errors:

I’ve tried the same with Jupyter Notebook and it works as expected. Is there any known issue with JupyterLab or am I missing something?

Thanks

I have it installed. In the logs I sent, the first error is that failed to activate jupyter-widgets The extensions I have installed are the following

JupyterLab v1.0.2
Known labextensions:
   app dir: /opt/anaconda2/envs/jupyterlab/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v1.0.1  enabled  OK
        wit-widget v1.3.0  enabled  OK

Based on the last comment, it seems reinstalling the widget with the necessary extensions worked, so closing this issue.

For anyone else who may still be facing the issue, note that the What If Tool has moved into a separate repository, so please file an issue at https://github.com/PAIR-code/what-if-tool/issues/new for reporting issues.
