RuntimeError: "sigmoid_cpu" not implemented for 'Long'. What is the issue here?

[mrittrukhuda (Mariha Tabassum)]

can somebody tell me why the error comes?!

or i will choose simple matrix!

[mrittrukhuda (Mariha Tabassum)]

ohh it is solved no need to answer! I forgot to use floating-points dtypes!

Hey @mrittrukhuda, while initializing the tensor use 30., 2. (This creates a FloatTensor) instead of 30, 2 (This creates a LongTensor) which might not be supported by many methods.

This is the error i am getting after i have uncommented the rotation, randomsize and colour jitter and running this cell

show_batch(train_dl)

whenever I’m trying sin in a tensor , it’s showing this error …

[Sebgolos (Sebastian)]

I’m guessing you created the tensor incorrectly.

Try changing the dtype to float (whatevernameforyourtensor.float())
