AWS 上的 jupyter 笔记本

Question

I have set up a Jupyter notebook on an AWS box, or so I thought. When I try jupyter notebook , however, I get this:

[C 16:22:30.841 NotebookApp] The 'kernel_spec_manager_class' trait of instance must be a type, but 'environment_kernels.EnvironmentKernelSpecManager' could not be imported

Any suggestions on how to fix?

EDIT actually, when I run jupyter notebook in the base environment, it works (I can't connect to it, but that's obviously a separate problem). However, in a "nonstandard" environment, it does not start. To answer the questions, this is an ubuntu 18.04 deep learning image, and in the environment I had installed jupyter and jupyterlab (via anaconda)

Answer 1

The issue seems to be same as the one described here:

• environment_kernels.EnvironmentKernelSpecManager could not be imported

Since in your question you have not indicated that you've tried that, I think that the solution proposed in the link could be tried:

pip install environment_kernels
