environment setup has invalid section in yaml and dependency conflicts on Ubuntu 22.04 with CUDA GPU

[rbavery]

👋 I'm poking around the yaml to see what the fix is for my machine, not sure if others are running into this. I'm using the latest version of mamba.

I can install from the lockfile successfully following these instructions, might be an upstream issue with mamba or how a dependency specifies it's own dependencies. https://clay-foundation.github.io/model/getting-started/installation.html#advanced

You're hitting into 2 separate dependency solving issues:

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package torchgeo-0.5.2-pyhd8ed1ab_0 requires segmentation-models-pytorch >=0.2, but none of the providers can be installed
  - package pylance-0.14.1-py311h6a0c370_0 requires pyarrow >=12,<15.0.1, but none of the providers can be installed

The first one is because torchgeo depends on smp which has a hard pin on timm=0.9.2 (conda-forge/segmentation-models-pytorch-feedstock#22 (comment)). Second one is lancedb=0.10.2 depends on pylance=0.14.1 which has a upper pin on pyarrow<15.0.1.

I've opened a PR to refresh the lockfile at #310. Could you test installing from that branch and run through a few examples?

The new lockfile worked for me (macOS).
