Error installing Cosmosis locally

[simran2296]

I am trying to install Cosmosis locally using mamba instructions here

I get following:

mamba install -y cosmosis cosmosis-build-standard-library

Pinned packages:

Could not solve for environment specs The following packages are incompatible ├─ cosmosis does not exist (perhaps a typo or a missing channel); └─ cosmosis-build-standard-library does not exist (perhaps a typo or a missing channel).

The installation of cosmosis-build-standard-library depends on the tensorflow package, because of baccoemu. Unfortunately, tensorflow does not yet work with Python 3.12 (there is a long discussion on the tensorflow github site about getting it to work).

One thing that should work is to install cosmosis and cosmosis-build-standard-library into a new environment; that should then pick up Python 3.11, and the installation should then complete.

Another option is to downgrade the version of Python in your current environment to Python 3.11 with: mamba install python==3.11, and then to install cosmosis and cosmosis-build-standard-library. But the developers of Mamba and Conda generally recommend using different environments for different projects, just to avoid this kind of problem.

[simran2296]

For the first option, I am trying to install it in a new environment and still get the same error message. For the second option, My current Python version is already 3.11.

[marcpaterno]

Can you please post the full command and output you get from the second option (creating a new environment)?

Near the beginning is the indicator of the issue: the output from your conda create -n gw -c conda-forge mamba shows that conda will install python 3.12.2. The problem is that when you create the environment, the only package you are installing is mamba. When you later try to install cosmosis and cosmosis-build-standard-library into this environment, it fails because the environment already contains Python 3.12.2.

Please try instead (you'll have to either remove the gw environment, or choose a different name for the new enviroment),

conda create -n gw cosmosis cosmosis-build-standard-library

This should create an environment named gw that contains both of them, and which contains python 3.11.x.
