"SyntaxError: Generator expression must be parenthesized" when trying to use conda

Question

I'm facing this problem whenever I'm trying to access any anaconda command. In fact, when I try to open my virtual environment it's showing there too

I have re-installed my anaconda navigator but still no result

C:\Users\Gagan Singh>activate tensorflow1

    from cytoolz.dicttoolz import merge
ModuleNotFoundError: No module named 'cytoolz'

During handling of the above exception, another exception occurred:

Answer 1

In my case, pip3 uninstall conda solved the problem.

The reason was miniconda trying to use pip's executables. It happened when I installed conda using pip3 first and then using miniconda.
