Single bash script that runs the full validation flow against the image:
1. Host pre-flight: docker version, nvidia-smi, nvidia-container-toolkit
runtime registered with docker.
2. Build the image (auto-detects the build context -- current dir,
docker/ subdir, or clones the docker-blackwell-build branch into
/tmp/unsloth-pr/).
3a. Smoke test: 5-step LoRA on Llama-3.2-1B-Instruct-bnb-4bit.
3b. Real workload: gpt-oss-20B fine-tuning notebook from
unslothai/notebooks, patched to max_steps=10, with the three
pre-train demo generations dropped for brevity. Auto-installs
triton_kernels at the SHA the upstream notebook pins for MXFP4.
All output is teed to /tmp/unsloth-docker-test/ (or --log-dir).
Usage:
bash docker/test_locally.sh # full run, ~15 min
bash docker/test_locally.sh --skip-notebook # blocks 1-3a only, ~3 min
bash docker/test_locally.sh --skip-build # reuse existing TAG
TAG=my:tag HF_TOKEN=hf_xxx bash docker/test_locally.sh
Each block fails fast with the exact log path to paste back.
