Axolotl#

此示例使用的配置与 OpenAccess-AI-Collective/axolotl 中的配置相同

简单的训练示例

HF_TOKEN=abc sky launch -c axolotl axolotl.yaml --env HF_TOKEN -y -i30 --down
ssh -L 8888:localhost:8888 axolotl
sky down axolotl -y

启动非托管的 Spot 实例（无自动恢复；适用于调试）

HF_TOKEN=abc BUCKET=<unique-name> sky launch -c axolotl-spot axolotl-spot.yaml --env HF_TOKEN --env BUCKET -i30 --down
ssh -L 8888:localhost:8888 axolotl-spot

启动托管的 Spot 实例（自动恢复；适用于完整运行）

HF_TOKEN=abc BUCKET=<unique-name> sky jobs launch -n axolotl-spot axolotl-spot.yaml --env HF_TOKEN --env BUCKET
