Packagesnotfounderror: the following packages are not available from current channels:

Question

Problem :

I am very much new to the Python. I have already tried to use it in a bunch of projects, but was not really needed to stray from the standard setup. I want to install some new packages to get access to the necessary functions for my project. But when I try to install it, I am getting the following error:

(base) C:\Anaconda2\Jupyter>conda install -c python-control -c cyclus slycot control

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - slycot

  - control

Current channels:

  - https://conda.anaconda.org/python-control/win-64

  - https://conda.anaconda.org/python-control/noarch

  - https://conda.anaconda.org/cyclus/win-64

...

And many of other channels similar to that above.

Does anyone have any solution on this Issue?

Please add the conda-forge channel to your list of channels with the use of following command:

 conda config --append channels conda-forge.

It will inform conda to also look on the conda-forge channel when you try to search for packages. After that you can just install the two packages with following command:

conda install slycot control.

The channels are the servers for people to host the packages on and the community-driven conda-forge is usually the good place to start with when packages are not available via the standard channels. I have already checked that both slycot and control are available there.
