Hi, thanks for this gist.
while compiling this code I am getting error.(below-error-log).

python convert-mat.py SynthText.h5

<KeysViewHDF5 ['data']>
Traceback (most recent call last):
  File "convert-mat.py", line 17, in <module>
    data[i] = fd[i][...]

Would you please help to solve this problem.

Hello,
when i run
python convert.py trainedNet.mat
it converts the file into trainedNet.h5 but is it a correct conversion?
as i am getting error:

tid = h5t.py_create(dtype, logical=1)
  File "h5py\h5t.pyx", line 1634, in h5py.h5t.py_create

please resolve this issue

Hi @AgriPooja , is it possible to share you .mat files? I can have a try with it.

Hello, i am not able to share the .mat files here.
