uninstall error about jupyterlab_tensorboard

[yaogang2060]

If I run jupyter lab --core-mode in bash,then it's all right.

If I reinstall this extension,the http://localhost:8888/lab is also blank.

Well, jupyterlab_tensorboard need this project jupyter_tensorboard as pre-request. So we need install jupyter_tensorboard at first, that's why you got 404 error(no backend for tensorboard). You can also use jupyter nbextension list to check the jupyter_tensorboard info. If you uninstall the jupyterlab_tensorboard, please using jupyter labextension list to make sure the jupyterlab_tensorboard is already diasbaled or removed. if not, using jupyter labextension disable jupyterlab_tensorboard disable it and then launch your jupyterlab. :)

Thank you.
It seems I made a mistake.I have 2 conda environments,one is base,one is tensorflow, I install jupyter_tensorboard in the tensorflow environment and not in the base environment, and my jupyterlab is in the base environment, so the base python cannot find jupyter_tensorboard to import.
I just install jupyterlab in tensorflow environment, then there is nothing wrong.

Another little problem:Can you update to jupyterlab version 0.34,the icon style problem:
