It may be that your condas channels need a wakeup call     with  conda update --all   For me it worked  More information  https   www anaconda com keeping-anaconda-date

Conda itself provides a quite detailed guidance about installing non-conda packages  Details can be found here  https   docs conda io projects conda en latest user-guide tasks manage-pkgs html   The basic idea is to use conda-forge   If it doesn t work  activate the environment and use pip

Have you tried   pip install  lt package gt    or  conda install -c conda-forge  lt package gt

Try adding the conda-forge channel to your list of channels with this command  conda config --append channels conda-forge  It tells conda to also look on the conda-forge channel when you search for packages  You can then simply install the two packages with conda install slycot control   Channels are basically servers for people to host packages on and the community-driven conda-forge is usually a good place to start when packages are not available via the standard channels  I checked and both slycot and control seem to be available there

If your base conda environment is active      in which case   base   will most probably show at the start or your terminal command prompt        and pip is installed in your base environment       which it is    conda list   grep pip       then install the not-found package simply by   pip install  lt packagename gt
