Error while converting a list into a numpy array

Question

I have a list

len(list) = 9260  
list[0].shape = (224,224,3)  

Now when I try to convert it to a numpy array, 

x = np.array(list)  

I get the following error:

ValueError: could not broadcast input array from shape (224,224,3) into shape (224,224)  

Answer 1

The only possible reason I could think of with this error is that probably one of your list element is not 3 dimensional. Have a closer look at your list, its data structure.

Thanks, @Rhea, that was the exact same issue with my list. The inner array, one element wasn't a 3 dimensional.
