In Matlab R2021b, I have problems running my python code. This problem did not exist in R2021a.
I get an error
"Unable to return the number of named arguments if not in an active function. "
I have a class defeinition, with variables and functions, written in python. The actual class connects to an webservice api.
For example I tell matlab to run python, run the api.py file, and create the class object main(). Set the output of this to a variable.
>> pobj = py.api.main()
If I want to retrieve 'data' which is a class variable I use:
>> pobj.data
The above works fine in both R2021a and R2021b.
The problem is if I want to run a class function 'func'
>> pobj.func()
In R2021a this would work.
In R2021b I get the error
"Unable to return the number of named arguments if not in an active function."
Please assist me to find a solution.
