scipy.io typeerror:buffer too small for requested array
- by kartiku
I have a problem in python. I'm using scipy, where i use scipy.io to load a .mat file. The .mat file was created using MATLAB.
listOfFiles = os.listdir(loadpathTrain)
for f in listOfFiles:
fullPath = loadpathTrain + '/' + f
mat_contents = sio.loadmat(fullPath)
print fullPath
Here's the error:
Traceback (most recent call last):

TypeError: buffer is too small for requested array
The whole thing is in a loop, and I checked the size of the file where it gives the error by loading it interactively in IDLE.
The size is (9,521), which is not at all huge. I tried to find if I'm supposed to clear the buffer after each iteration of the loop, but I could not find anything.
Any help would be appreciated.
Thanks.
