Am using Anaconda 3 (conda version : 4.8.2, conda-build version : 3.18.9) - Jupyter Notebook environment with python (v3.7.4).

Am trying to upgrade scikit-learn package to 0.22.1, but am continuously encountering below error:

Command used: conda install scikit-learn=0.22.1

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

  • 0.22.1

Current channels:

To search for alternate channels that may provide the conda package you're looking for, navigate to

Can someone please help me with this issue! Thanks in advance!

The error message hints towards an additional space in scikit-learn=0.22.1. But your installation command seems correct. Can you double check that again? Can you copy-paste conda install scikit-learn=0.22.1 into your command line? – cel
No luck! Still the same error! In fact, this error is specific to 0.22.1; If am trying any previous versions like v0.21.3, they are successfully downloaded and installed. – alekhya
I was able to find at least one package: scikit-learn 0.22.1 py37h6288b17_0 – AMC

I had a similar problem where conda didn't recognized there is a newer version and just didn't update sklearn. I'm not sure it will solve your problem, but I think it will and I suggest you try the following solutions:

  1. It seems your channels are bit different then mine (I'm also using win10 64bit) Try running:

    conda config --append channels conda-forge
conda install scikit-learn=0.22.1

  2. If step 1 fails, run:

    conda update conda
conda install -c conda-forge scikit-learn

  3. Follow the solution in here Cannot update python package on anaconda to latest version (given by lucasgcb), I recommend closing all of the running conda envs first. If the path contains spaces don't forget to add "" around the path.

In my case solution 3 do the trick, but I got a different error than you:

Updating scikit-learn is constricted by

anaconda -> requires scikit-learn==0.22.1=py37h6288b17_0
