Please fill in the following for any issues

Your setup:

1. Operating System (Linux, MacOS, Windows): MacOS
2. Hardware type (x86, ARM..) and RAM: M2 8 gb RAM
3. Python Version (e.g. 3.9): 3.11.5
4. Caiman version (e.g. 1.9.12): N/A
5. Which demo exhibits the problem (if applicable): installing mamba
6. How you installed Caiman (pure conda, conda + compile, colab, ..): n/a
7. Details:

When I install mamba it gives me the error message in the title: The following packages are causing the inconsistency: - defaults/osx-arm64::conda-build==24.1.2=py311hca03da5_0.

It then tries flexible solves and says the following: The following packages are causing the inconsistency:

• defaults/osx-arm64::anaconda-navigator==2.6.0=py311hca03da5_0
• defaults/osx-arm64::conda-build==24.1.2=py311hca03da5_0
• defaults/noarch::conda-token==0.4.0=pyhd3eb1b0_0

If I press y and install it then every terminal command becomes accompanied by the following error:

I've already restarted my base and tried a similar route, but I have no clue what to do. I'm happy to restart anything or redownload anaconda, but hopefully there's a better solution. Thanks.

I'll need to write new install instructions; nowadays I recommend miniforge, which will avoid issues with installing mamba (as it's already present with that distribution of conda) and will avoid most packages from the defaults channel.

[noah08642]

Hi, thanks for the tip. Could you share some basic instructions for someone unfamiliar with using mini forge?

[pgunn]

The new instructions would look roughly like this:

Don't start with the normal anaconda or miniconda installers; instead do a websearch for miniforge3 and install that (if someone doesn't have any environments they care about but has anaconda3/miniconda3, they can carefully remove that first, including .condarc, the data dirs, and the shell dotfile integration).

After installing miniforge3 and opening a new shell, they'll have a mamba command as well as the conda command and can follow through the existing caiman instructions but skipping up until the parts right after installing mamba; everything after that should be the same.
