add LibMambaUnsatisfiableError to Installation Troubleshooting

[raybellwaves]

Just tried a fresh install on my old PC (has a lil GeForce GTX 1060 6GB) using conda and got LibMambaUnsatisfiableError. It took me a couple of minutes to understand what the error was telling me. I made a note of it here to help others who may come across it. Happy to have feedback on the wording or you are welcome to edit as you see best.

Edit: I didn't build the docs locally but looks as expected in the preview.

@raybellwaves Thanks for the idea. This is also covered in the system requirements for CUDA versions, would that have answered your question equally well if we expanded the notes on CUDA 12 to say that CUDA 12 conda packages require a driver that supports CUDA 12? https://docs.rapids.ai/install#system-req

Also RAPIDS 24.02 has dropped support for Pascal GPUs, which includes the GTX 10xx series. You will need to use RAPIDS 23.12 for proper functionality. https://docs.rapids.ai/notices/rsn0034/

Thanks for responding @bdice. I see the section at https://docs.rapids.ai/install#system-req and a bit more detail wouldn't have hurt. I think my preferred solution would be using the selector tool at the top and then having a link generated at the bottom of the tools that hyperlinks to issues if a user comes across them (i'll create a new issue: #490).

Thanks for the note on Pascal. https://github.com/rapidsai/cudf/blob/branch-24.04/python/cudf/cudf/utils/gpu_utils.py#L81 caught it which was great.

One proposal for improvement.

@raydouglass Would you take a peek at this and decide if this is the right place to document this?

@raydouglass Your changes look good to me, so I'll merge.

Thanks @raybellwaves for the issue report and PR!
