Could not find or load class error on startup

[BrianHanechak]

In versions 1.0.5 through current, when I try to start mxnet-model-server on my Windows box, I get the following error:

Error: Could not find or load main class com.amazonaws.ml.mms.ModelServer

If I downgrade to 1.0.4 or earlier, I am able to start it correctly.

@BrianHanechak : Thanks for reporting this. We will look into this.

Hey,

I am also facing the same issue on Windows 10:-

• multi-model-sevrer version == 1.1.0

I tried downgrading to version 1.0.4, but it looks like that version is no longer supported. The minimum version that I could saw was 1.0.8.1. I tried downgrading from my current version to this and did the same steps again, but still facing the same issue.

Any pointers/help would be highly appreciated.

Thanks Shaksham

What is the status of this issues? This seems to happen when installing MMS in dev mode (pip install -e .)

This is happening due to this line: https://github.com/awslabs/multi-model-server/blob/4d45a1c51e414c5d8bbfecc99b3b460de221f6f5/mms/model_server.py#L103

because the forward slashes don't work in windows. For it to be OS independent, it should be something like this:

".;{}".format(os.path.normpath(os.path.join(mms_home, "mms/frontend/*")))

Still have the same error after the modification from @mikeobr, any progress about this error?

The fix should be like: ".{}{}".format(os.pathsep, os.path.join(mms_home, "mms", "frontend", "*")) to be os independent. There's an issue with the path separator and path component separator.
