Show mamba commands directly instead of a conda-then-swap note#1827ramakrishnap-nv wants to merge 5 commits into
Conversation
The docs recommended mamba but printed conda commands with a "replace conda with mamba" aside, so the recommended path required an extra mental substitution on every command. Lead with mamba for env creation; keep conda for activation, which mamba doesn't implement. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

| 1. **Check CUDA driver compatibility.** Run `nvidia-smi` and read the *CUDA Version* in the top-right corner — that's the maximum CUDA your driver supports. Pick a conda env file from `conda/environments/all_cuda-<ver>_arch-<arch>.yaml` whose CUDA major version is **≤** that. A mismatch builds successfully but fails at runtime inside RMM with `cudaMallocAsync not supported with this CUDA driver/runtime version` — verify this *before* the build, not after. | ||

mamba (v 2.5.0) supports activate.

Good catch, thanks — you're right, that was based on a local mamba 1.4.2 test without mamba init run first, not an actual limitation. Fixed in 73c840a: dropped the incorrect claim, kept conda activate in the example since it works regardless of mamba version/init state, and noted mamba activate is fine too where supported.
The mamba note didn't say which of the two installers just mentioned (miniforge, miniconda) actually includes it, so miniconda users had no signal that the mamba commands below would fail without an extra install step. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
CI Test Summary⏭️ All 5 test job(s) skipped. |
Per review: mamba does support 'mamba activate' (confirmed against mamba's own docs, which present it as the standard approach with no version caveat). The earlier wording was based on a local mamba 1.4.2 test that hadn't run 'mamba init' first, not an actual limitation of mamba. Keep 'conda activate' in the example since it works regardless of mamba version or init state, but stop asserting mamba can't do it. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Consistent with leading with mamba for env creation: show 'mamba activate' in the example, with an inline comment pointing to 'conda activate' as the fallback for setups where mamba init hasn't been run. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
