conda install matplotlib results in huge list on incompatibilities-CodePudding

I have a conda env that I build from a requirements.yml file that I obtained from a classmate so we could work on a project together. I tried installing matplotlib and it resulted in a gigantic list of incompatibilities that I don't think I could even start tackling manually.

Here are the most important packages I'm using (the ones that have come up in a few other posts I've looked at and what the error looks like):

python 3.9.7
tensorflow 2.6.0
anaconda 4.11
numpy 1.21.2
tornado 6.1

Is there a way of adressing this without going into every line of the error?:

The part of the error containing matplotlib incompatibilities specifically:

CodePudding user response：

Create separate conda environments. keras-tf should be in a separate environment from (base), which you're doing, but you may want to create it from scratch.
When creating an environment from scratch, conda works out the correct dependencies, but if installing from a requirements file, specific versions are being forced. If the yml file being used wasn't from conda, there may be version conflicts.
The more packages with a specific version, the more likely there is to be an version conflict.
