Install on mac m1 encountered with Could not solve for environment specs

[Maydaytyh]

• I read the conda-forge documentation and could not find the solution for my problem there.

Issue: Hi, I have installed conda on my m1 mac before, then I install it with the newest script, but I encountered the following error, can you help me?

[hmaarrfk]

I'm not sure "what" exactly the newest script is. Can you please be explicit and state the name of the file you used (and likely when you downloaded it).

Finally, can you provide us the output of the command:

cat ~/.condarc 

PS. I understand that you think the issue is debuggable within your screenshot, but often clues to the errors happen much before the loudest error. Could you please copy and paste the full error log, along with the command you used to attempt to "install"

[gongx030]

I had the similar problem with M1 macbook pro (16-inch 2021):

ERROR   Could not solve for environment specs

Also tried to install tensorflow-deps through miniconda on macos-arm64. The installation of miniconda had no issues, however, the installation of tensorflow-deps had a lot of different conflicting issues.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.9 from "/Users/gongx030/mambaforge/bin/python"
  * The NumPy version is: "1.19.5"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Hi, as reported here, if you already have conda-related stuff installed on your mac, you might encounter some problems.
I was able to update conda on my M1 mac just following what xhochy suggested.
Hope this helps

@mattfack Thanks for your suggestions. Removing ~/miniforge and reinstall everything works for me.

If you'd prefer that conda's base environment not be activated on startup,
   set the auto_activate_base parameter to false:

conda config --set auto_activate_base false

Thank you for installing Miniforge3!

However, with the default python 3.9, I still had the aforementioned numpy issue. Using a python version of 3.8 and a numpy version of 1.20.0 solved the issue. Now I am able to run the mnist example and see the GPU usage in the Activity Monitor.

==> Dependencies
Build: pkg-config ✔
==> Caveats
ncurses is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ncurses first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/ncurses/bin:$PATH"' >> ~/.zshrc

For compilers to find ncurses you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/ncurses/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/ncurses/include"

For pkg-config to find ncurses you may need to set:
  export PKG_CONFIG_PATH="/opt/homebrew/opt/ncurses/lib/pkgconfig"

For all dears;

I tried and I want to say:

You can try to delet all files & folders which name includes conda, and don't forget to delet .conda & .condarc, the hidden files & folders.

Something happened between v4.11.0-0 and v4.11.0-1 (as rishi-kulkarni suggested).

Reverting to the last version that worked (https://github.com/conda-forge/miniforge/releases/download/4.11.0-0/Mambaforge-4.11.0-0-Linux-x86_64.sh) fixed the issue.

We get the same error with Redhat RHEL v8.5 on x86_64 ("nothing provides ncurses >=6.2,<6.3.0a0 needed by") when installing versions v4.11.0-1, v4.11.0-4 and v4.12.0-0.

Our setup has a global /etc/conda/.condarc (which among other things sets 'default_alias' globally), and everything worked fine with v4.11.0-0. The issue seemed to be affected by a mixture of 'default_alias', 'channels' and 'default-channels', but reverting back to v4.11.0-0 simply made the installation run as usual.

This is also happening on Oracle Linux Server 7.9 x86_64
