Installation error in deeplabcut: `kernel_spec_manager_class` not recognized by `EnableNBExtensionApp`

Hey everyone,

I followed the installation instruction: here:DeepLabCut/installation.md at 87e18282c0ea354780cbf16ddfed85869a887664 · DeepLabCut/DeepLabCut · GitHub.

However, no matter whether CPU or GPU version installation I followed (I have a nvidia gpu), there was always errors like this:

Enabling nb_conda_kernels…
CONDA_PREFIX: G:\STUDY\Anaconda3\envs\DLC-GPU
Status: enabled

Config option kernel_spec_manager_class not recognized by EnableNBExtensionApp.
Traceback (most recent call last):
File “G:\STUDY\Anaconda3\envs\DLC-GPU\Scripts\jupyter-nbextension-script.py”, line 10, in …
ImportError: DLL load failed: The specified module could not be found.

Anyone know how to solve this?? thank you!
