I don’t get it why its throwing this error ?
I reckon this is the way ?
i tried in doing by generating random values it works.
import torch

batch_size = 5
nb_digits = 10
# Dummy input that HAS to be 2D for the scatter (you can use view(-1,1) if needed)
y = torch.LongTensor(batch_size,1).random_() % nb_digits
# One hot encoding buffer that you create out of the loop and just keep reusing
y_onehot = torch.FloatTensor(batch_size, nb_digits)

# In your for loop
y_onehot.zero_()
y_onehot.scatter_(1, y, 1)

print(y)
