Multiple images for testing

[gaurav16gupta]

Hi, How can I pass multiple images as batch while testing? I made these changes in use_dictnet.py line 44, just to check if I can provide multiple images.

def classify_image(self,img):
img = self._preprocess(img) xtest = zeros((1,2,32,100)) xtest[0,0,:,:] = img xtest[0,1,:,:] = img z = self.model.predict_classes(xtest,verbose=0)[0] return self.output_word[z][0]

I get the following error:
