Hi
I am trying to use this line
py.intervals.py();
Where intervals is a python script. I get the error
>> py.intervals.py()
Undefined variable "py" or class "py.intervals.py".
I am using R2018b. Do I need to purchase a Python Libraries API?

Yes I have seen the Python Libraries. I got the errors
Import argument 'intervals.py' cannot be found or cannot be imported.

Hi,
I see two possible corrections you could try. Firstly try calling the python module itself instead of the file name (like "py.mymod.search(N)" instead of "py.mymod.py").
Secondly, maybe your file isn't in the python search path. If it isn't, try adding your folder to the python sys path using:
if count(py.sys.path,'') == 0
insert(py.sys.path,int32(0),'');
end

My solution:
% Simple way to load your library
copyfile(my_library_file_path, pwd, 'f');
% It's necessary to load library
py.my_library.any_method_or_function();
delete 'my_library.py';
Now, your Python library is loaded to use in any directory.
