Reading python pickle of dict in MATLAB causes error
显示 更早的评论
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)])
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?

According to matlab documentation, the fieldnames for structure have the following requirements, which your data does not meet.
field — Field name
character vector | string scalar
Field name, specified as a character vector or string scalar. Valid field names begin with a letter, and can contain letters, digits, and underscores. The maximum length of a field name is the value that the namelengthmax function returns.

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)

You can see this answer on how you can convert your dictionary into a Matlab type containers.Map.

Map containers might be what you're looking for.
