Making three dimension numpy from two dimention list-CodePudding

I want to make three dimension np (50, 917, 100) finally.

Now,I have variable sentence which has two dimention less than 917.

ex)

(812,100),(917,100),(250,100),(240,100),(560,100),,,,

So, I want to stack these variables to np variable and 0 padding where shorter..

res = np.zeros((50,917,100)) # Initialize the empty numpy
print(res.shape)

for sentence in all_sentences: # len(all_sentences) = 50   
   res.append(sentence)  #but it is wrong.

How can I do this ???

CodePudding user response：

appending would mean you stack those after your array of zeros. What you want to do instead is overwriting the respective parts in your initialized array:

for i, sentence in enumerate(all_sentences):
    res[i,:sentence.shape[0],:] = sentence
