Error occurs calling install_gluonts() on arm64 Mac M1.

It seems like there are some pacakges are not available in 3.7 Python channel. The error code is the following:

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

  - python=3.7.1

Current channels:

  - https://conda.anaconda.org/conda-forge/osx-arm64
  - https://conda.anaconda.org/conda-forge/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.

Error: Error creating conda environment 'r-gluonts' [exit code 1]

Using the develope version of reticulate pacakge to install miniconda, the Python version is 3.8.12.

Here is my python information calling reticulate::py_discover_config()

python:         /Users/username/Library/r-miniconda-arm64/envs/r-reticulate/bin/python
libpython:      /Users/username/Library/r-miniconda-arm64/envs/r-reticulate/lib/libpython3.8.dylib
pythonhome:     /Users/username/Library/r-miniconda-arm64/envs/r-reticulate:/Users/username/Library/r-miniconda-arm64/envs/r-reticulate
version:        3.8.12 | packaged by conda-forge | (default, Oct 12 2021, 21:25:50)  [Clang 11.1.0 ]
numpy:          /Users/username/Library/r-miniconda-arm64/envs/r-reticulate/lib/python3.8/site-packages/numpy

Any suggestions? Thanks!

I'd try following the Installation Guide here, which has troubleshooting guidance for the Python Environment and details on how to set up custom environments.

As of this message, the major requirements are:

• gluonts>=0.8.0 (required for modeltime.gluonts >= 0.3.0). Note that I test with gluonts==0.8.0, so I recommend that version.
• mxnet~=1.7
• pandas
• numpy
• pathlib
• ujson

I tried the above approach by calling:

reticulate::py_install(
    envname  = "my_gluonts_env",
    python_version = "3.8.12",
    packages = c(
        "mxnet~=1.7",
        "gluonts==0.8.0",
        "pandas==1.0.5",
        "numpy",
        "pathlib==1.0.1",
        "ujson==4.0.2"
    ),
    method = "conda",
    pip = TRUE
)

and the error is:

ERROR: Could not find a version that satisfies the requirement mxnet~=1.7 (from versions: 1.6.0)
ERROR: No matching distribution found for mxnet~=1.7
Error: Error installing package(s): "'mxnet~=1.7'", "'gluonts==0.8.0'", "'pandas==1.0.5'", "'numpy'", "'pathlib==1.0.1'", "'ujson==4.0.2'"

[mdancho84]

MXNet is up to 1.9.0 on pypi so pip should be able to install it. Maybe try changing to 1.9.0.

[chenx2018]

I think the only available version of mxnet is 1.6.0 as the error message shows:

ERROR: Could not find a version that satisfies the requirement mxnet~=1.9.0 (from versions: 1.6.0)
ERROR: No matching distribution found for mxnet~=1.9.0
Error: Error installing package(s): "'mxnet~=1.9.0'", "'gluonts==0.8.0'", "'pandas==1.0.5'", "'numpy'", "'pathlib==1.0.1'", "'ujson==4.0.2'"

same here. Any news?

I think the only available version of mxnet is 1.6.0 as the error message shows:

ERROR: Could not find a version that satisfies the requirement mxnet~=1.9.0 (from versions: 1.6.0)
ERROR: No matching distribution found for mxnet~=1.9.0

[mdancho84]

Are you using M1? I believe that is the problem.

I got it to work by using the older R & Rstudio that isn’t optimized for M1. Thus using Rosetta. @mdancho84
