# dagster-plus
I'm running into an issue with lightgbm on dagster cloud. I have had lightgbm in my requirements.txt, but I just now added code that called it (in a branch deployment). My code location didn't load, and returned "OSError: libgomp.so.1: cannot open shared object file: No such file or directory". It looks like the fix is easy if I had control over the dockerfile: https://stackoverflow.com/questions/55036740/lightgbm-inside-docker-libgomp-so-1-cannot-open-shared-object-file. I'm not sure what I can do myself though. How can I fix this?
Full stack trace when loading the code into my branch deployment:

This is for a serverless or hybrid deployment? There’s a couple options for customizing the base image to include deps like this
cool, thanks!
Got it. So I just need to build my own docker image and then tell dagster where to find it?
Correct, if you’re using the new python executable (pex) deploys
Okay. Sounds good. Thanks!
