export matlab data to python
I have a sentence ' i am unhappy' stored in variable 'a' in matlab. i want to extract data from matlab to python.
like if i write 'a' in python, it should display the whole sentence stored in MATLAB. and yes further i want to convert that sentence into speech using gtts.
i have tried,this:
from scipy.io import loadmat
test = loadmat('value.mat')
but it gives error:
MatReadWarning: Duplicate variable name "None" in stream - replacing
previous with new Consider mio5.varmats_from_mat to split file into
single variable files matfile_dict = MR.get_variables(variable_names)
python import export workspace

I could test it like this and had no problems:
In matlab:
>> a = ' hello mat file'
a =
hello mat file
>> filename = 'test.mat'
filename =
test.mat
>> save(filename)
and then in python:
import scipy.io as scio
data = scio.loadmat('test.mat')
data
Out:
{'__header__': b'MATLAB 5.0 MAT-file, Platform: PCWIN64, Created on: Tue Nov 27 10:20:58 2018',
'__version__': '1.0',
'__globals__': ,
'a': array([' hello mat file'], dtype='<U15'),
'filename': array(['test.mat'], dtype='<U8')}
data['a']
Out: array([' hello mat file'], dtype='<U15')
So no error message here.
However, note that in Matlab save by default saves all content of the current workspace in the mat-file. Could it be possible, that you have created some other variables which perhaps are of an unsupported type?
You could check by simply explicitly saving only your test variable a:
save(filename, 'a')
Does this lead to an importable mat-file in python?
