Problem installing miniconda3 on M1 Mac

Product Help
1

Hi,

I am trying to install miniconda3. I have a Mac M1. Installation is successful but when I try and install a new package I get the following error message:

“UserWarning: zstandard could not be imported. Running without .conda support.
warnings.warn(“zstandard could not be imported. Running without .conda support.”)”

I am currently running it in the Rosetta mode. Does anyone have any advice as to how to solve this issue?

We will gladly help you, Anaconda is compatible with the M1 chip so that wouldn’t be a problem, please try to uninstall Anaconda and install it again, you can download your compatible version here:

I’m going to leave you the installer here for your platform so that you can install it:

https://repo.anaconda.com/archive/Anaconda3-2023.03-MacOSX-arm64.pkg

There is the x86 installer as well:

https://repo.anaconda.com/archive/Anaconda3-2023.03-MacOSX-x86_64.pkg

It’s also advisable to completely uninstall Anaconda before proceeding with the installation to make sure to get rid of any errors, you can do that if you follow these instructions:

macOS or Linux

  1. Open your terminal application.
  2. Remove your entire Anaconda directory with rm -rf. Depending on your installation, your anaconda2 or anaconda3 directory will be in your root folder or in your opt folder.

The following are a few examples of how you may need to delete your Anaconda folder

rm -rf anaconda3

rm -rf ~/anaconda3

rm -rf ~/opt/anaconda3

  1. Close and reopen your terminal to refresh it. You should no longer see (base) in your terminal prompt.

If you want here is a detailed explanation:

Hi @Carlos_Valin,

Thanks for the kind advice.

I think I have found a solution. I installed Anaconda3 for Apple Silicon following the link you provided. The installation was successful and I now longer get error messages.

I then created a separate conda environment that runs in Rosetta mode for the program I need to use, that is Mac Intel compatible. This seems to work so far
