Unable to find pytorch==1.11.0 from inside continuumio/miniconda3 Docker container-CodePudding

I'm trying to get pytorch==1.11.0 using the continuumio/miniconda3:4.12.0 Docker image.

I first run docker run -i -t continuumio/miniconda3 /bin/bash. Then, in the container, I run: conda search -c conda-forge pytorch==1.11.0. Here's the error:

No match found for: pytorch==1.11.0. Search: *pytorch*==1.11.0

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

  - pytorch==1.11.0

Current channels:

  - https://conda.anaconda.org/conda-forge/linux-aarch64
  - https://conda.anaconda.org/conda-forge/noarch
  - https://repo.anaconda.com/pkgs/main/linux-aarch64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/linux-aarch64
  - https://repo.anaconda.com/pkgs/r/noarch

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

    https://anaconda.org

and use the search bar at the top of the page.

I then tried conda config --append channels conda-forge before running conda search -c conda-forge pytorch==1.11.0 again. Got the same error.

To test the network connection I ran conda search pytorch, so it'd search the default channel for any pytorch package. It's successful:

Curiously, when I run conda search -c conda-forge pytorch==1.11.0 outside of the container, in my local terminal, it's available:

Loading channels: done

pytorch                       1.11.0 cpu_py39h19aa3d3_0  conda-forge

Why's this the case and how do we fix it?

CodePudding user response：

The "Current channels" in the error message showing linux-aarch64 indicates that the Docker image is arm64. Conda Forge only added such pytorch builds in v1.12.0; the anaconda channel does offer some earlier builds, but only up to v1.10.

Otherwise, maybe you didn't actually want an arm64 Docker image. In that case, one can specify the platform in docker CLI with the --platform argument, e.g., --platform=linux/amd64.

P.S. I'd use a Mambaforge container instead.
