How do I install Matplotlib 3.4.1 in Anaconda?

Question

I want to use a package only available in version 3.4.1. When I do conda list then I see my matplotlib version is 3.2.2.

I've tried conda.install matplotlib=3.4.1 but that return a PackagesNotFound Error across these channels:

Current channels:

  - https://repo.anaconda.com/pkgs/main/win-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-64
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-64
  - https://repo.anaconda.com/pkgs/msys2/noarch

I tried conda install --channel "conda-forge" matplotlib to get around that, but no luck. It says all packages are already installed. I don't understand why this doesn't work as the webpage https://anaconda.org/conda-forge/matplotlib indicates that the package is v3.4.1

Edit: I tried conda update matplotlib which updated mine to 3.3.4 but not 3.4.1... After looking at this documentation: https://conda.io/projects/conda/en/latest/user-guide/tasks/manage-pkgs.html# I tried using pip install matplotlib but that just specified a bunch of Requirement already specified: (...) statements with no upgrade to the installation

Any help appreciated.

Answer 1

I went to the Matplotlib official site discourse and found this post: https://discourse.matplotlib.org/t/matplotlib-announce-ann-matplotlib-3-4-1/21991

Using pip install matplotlib==3.4.1 worked! Originally I had tried pip install matplotlib=3.4.1 but using only a single "=" is wrong.

Answer 2

I tried with DavidD003 solution https://stackoverflow.com/a/66932922/11753330 and it worked also with conda command: conda install -c conda-forge matplotlib==3.4.2

In this way the update succeded. Before:

matplotlib                3.3.4            py38hecd8cb5_0  
matplotlib-base           3.3.4            py38h8b3ea08_0

After:

matplotlib                3.4.2            py38h50d1736_0    conda-forge
matplotlib-base           3.4.2            py38h6152e83_0    conda-forge
