I get the “packagesnotfounderror: the following packages are not available from current channels:” issue when trying to install some new packages to get access to functions necessary. Here is the detail of the error I got the error message:

(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
 
 ...

Please give me some advice to solve this problem.

    The cause: You get this error because you don’t add the conda-forge channel to your list of channels.

    The solution: To solve this error, you can try:

    pip install <package>

    or

    conda install -c conda-forge <package>

  2. This command conda config --append channels conda-forge will add the conda forge channel into your list. This command tells conda that it should also search for the condaforge channel while searching for packages. The two packages can be installed with conda install slycot control.

    Channels are servers that allow people to host packages. The community-driven Conda-forge is often a good place for packages to be hosted when they are not available on the standard channels. Both slycot as well as control are available, according to my testing.
