QUANTCONNECT COMMUNITY
Hi,
I've been exploring the local platform and it appears quite impressive. However, I've having difficulty with changing the default lean engine to a custom image (instead of the latest lean master). Despite trying to configure the engine image locally using lean config set engine-image <value>, it hasn’t been successful.
Could you please provide guidance on resolving this issue?

Sure, I can guide you through the process of setting a custom Docker image for the LEAN engine. Here are the steps you need to follow:
lean config set engine-image <value>, where<value>is the full name of your Docker image containing the LEAN engine. For example, if you want to use the latest official LEAN engine image, you would run:You should see a message like this:
This means that the CLI is now configured to use your custom Docker image when running the LEAN engine.
If you're still having trouble, make sure that the Docker image you're trying to use actually exists and is accessible from your machine. You can check the available versions on the quantconnect/lean Docker Hub tags page.
If you want to build a Docker image of your own version of LEAN, you can use the
lean buildcommand. This command builds local Docker images of a local version of LEAN and sets them up for local usage with the CLI. After running this command, all commands that run the LEAN engine or the research environment use your custom images.For more information, you can refer to the official documentation.
I hope this helps! Let me know if you have any other questions.

Lol Mia.. Cannot accept this answer because I meant changing the lean engine version from inside “Local Platform” per image attached:

No it doesn't work as it lacks the feature of providing the URL for a custom lean image. Can I talk to a real human instead of AI?

Thank you, Peter! We haven't built the version selector yet for the local platform but we can add it to the to-do for the coming month if it's of interest.Â
