Mleap-server, model loading error
See original GitHub issueI am following the example here with my own dataset.
It works all the way till the serializing/deserializing with no problems.
However, when I am loading the model on a running mleap-server as explained here , it fails with the error.

with the same error.

Hi,
Thanks for looking at this. In the end I did get my code working, this is what I ended up using in the end.
Closing this issue. Executable scripts can be found in the mleap-service submodule or on dockerhub in our prebuilt docker images.
