I have a pickle file of a python dictionary whose keys are tuples `(10, 11), (10, 12), (11, 10), (11, 12), (12, 10), (12, 11)`.
I use the following commands to read them
fid = py.open('file.pickle','rb');
data = py.pickle.load(fid);
At this point, I think the code is working correctly as
data.keys()
in MATLAB gives the correct answer as
dict_keys([(10, 11), (10, 12), (11, 10), (11, 12), (12, 10), (12, 11)])
The equivalent of dict in python is structures ([1]) so when I try to convert it to `struct` using
data=struct(data)
, I get an error as
Error using py.dict/struct
Field names must be non-empty character vectors or a string
scalars.
What does the error mean here?

Based on the output you have shown in your question, the keys are numeric values. As stated in the documentation matlab struct does not support these as field names. (see valid fieldname criteria)

Map containers might be what you're looking for.
