HI,
I was trying to use the library compiler to generate some .m files into python. I select the ffunctions and an example exection file(.m) as well as specified in the guide:
https://www.mathworks.com/help/compiler_sdk/gs/create-a-python-application-with-matlab-code.html
however, I see this error in the command window in matlab and ther eis no file generated in the folder
for_redistribution_files_only\samples
Here is the error message in cmd window: Please let mek now of any solutions to this. Thanks.

Are you compiling to Python package but get an error message of Java package (compiler_sdk/java)?
What your main function looks like?

I have nothing to do with java. I am trying to convert a bunch of .m files into python code. Here is the screenshot of the process I am using.
