It would be great if you share some details around it. </P> Thu, 19 May 2022 06:11:20 GMT Chakra03 2022-05-19T06:11:20Z https://community.databricks.com/t5/machine-learning/pytorch-ddp-on-databricks/m-p/21813#M1225 <P>Hello!</P><P>I am currently trying to use Pytorch Lightning inside Databricks and I am currently using a cluster with 2 gpus. Whenever I try to train my Transformer model with 1 gpu in DP strategy everything works fine, but when I try to use both the 2 gpus with a DDP strategy I get the following error:</P><P><I>MisconfigurationException: `Trainer(strategy='ddp_spawn')` or `Trainer(accelerator='ddp_spawn')` is not compatible with an interactive environment. Run your code as a script, or choose one of the compatible strategies: Trainer(strategy=None|dp|tpu_spawn). In case you are spawning processes yourself, make sure to include the Trainer creation inside the worker function.</I></P> Fri, 29 Apr 2022 13:42:55 GMT https://community.databricks.com/t5/machine-learning/pytorch-ddp-on-databricks/m-p/21813#M1225 Marco98 2022-04-29T13:42:55Z https://community.databricks.com/t5/machine-learning/pytorch-ddp-on-databricks/m-p/21814#M1226 <P>Hi @Marco Capusso​&nbsp;, I am facing the similar issue could you find some fix.
