Not able to install Spyder in the virtual environment on Anaconda
You should activate your virtual environment and then type: conda install spyder.  That should install spyder for that particular virtual environment. If you used pip or pip3 you may have problems.
I was trying to install spyder in the virtual environment on anaconda, but ended up with this debugging error.

Executing transaction: 
  \ DEBUG menuinst_win32:init(199): Menu: name: 'Anaconda${PY_VER} ${PLATFORM}', prefix: 'C:\Users\Public\Anaconda\envs\tensorflow', env_name: 'tensorflow', mode: 'None', used_mode: 'user'

I have also tried to clear the debugging errors using 
conda config --set quiet True , but no use.
Can anyone help me with this?
