I did a full uninstallation of an old version anaconda following the instruction on: https://docs.anaconda.com/anaconda/install/uninstall/,
and then installed the Anaconda3-2020.07-Windows-x86_64.exe version downloaded from anaconda website into D:\anaconda3,
then I created environment using:

conda create -n py3701 python=3.7
conda activate py3701 
conda install ipykernel=5.3.2  #(same ver as that in root env)
python -m ipykernel install --user --name py3701 --display-name "py_37_01"

However, after the env creation, I got different first python path when I switched into the env py3701:
d:\Anaconda3\python.exe shown in JUPYTERNOTEBOOK running !where pthon
d:\anaconda3\envs\py3701\python.exe shown in andconda prompt running where pthon

And soon I ran the following command in root env and found nb_conda_kernels has not ever existd in root conda environment after the installation of Anaconda3-2020.07-Windows-x86_64.exe .
My problem is: isn't nb_conda_kernels preinstall in root conda environment? I remembered it would be preinstall in root env while installing the old anaconda version.
