I am trying to append data to an existing .mat file in python. See the following code:
with open('train_x.mat','ab') as f:
scipy.io.savemat(f, {'data':image_data})
After appending is done when I am trying to load the file as:
training_x = scipy.io.loadmat('train_x')
It is showing the following error:
/usr/lib/python2.7/dist-packages/scipy/io/matlab/mio.py:135: MatReadWarning:
Duplicate variable name "data" 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)
Traceback (most recent call last):

raise TypeError('Expecting miMATRIX type here, got %d' % mdtype)
TypeError: Expecting miMATRIX type here, got 2375258764
The file is around 30MB. When I tried to open it in Matlab, it is showing following error:
Error using load
Unable to read MAT-file /home/sonu/Desktop/Code/train_x.mat. File might be corrupt.
I am not getting why is it happening, please help.
