Unable to synchronously open file
When I try to load my model.h5 file it returns this error on the deploy logs. I am deploying a Flask app API and all other routes have been working fine except this one.

you would have to store the file in an S3 storage bucket, then have your code download the model file for you

OSError: Unable to synchronously open file (file signature not found)how big is the model file?
hi, i manually created the model architecture at the api and now i'm trying to only load the model weights, which is 172MB. i used git lfs to mount it on github
just as I thought, railway does not support pulling files from git lfs

you would have to store the file in an S3 storage bucket, then have your code download the model file for you
I recommend cloudflare r2
ill check on that, thanks
