reading a cell is not supported and it should be mentioned in the documentation.
Here is the error:
terminate called after throwing an instance of 'std::runtime_error' what(): unknown data type (dtype: unknown (0); shape: [1,13233]; size: 0 bytes) for object named `0' at file `./results/LightenedCNN_C_lfw.mat'
Steps to reproduce:
from bob.io import matlab matlab.read_varnames('./results/LightenedCNN_C_lfw.mat')
where the file is in here.
I will update this issue as I debug more.
