when I Run this code I got this error:
Traceback (most recent call last):
  File &quot;&lt;stdin&gt;&quot;, line 24, in &lt;module&gt;
TypeError: expected CPU (got CUDA)

How to can I solve this error?

To transfer the variables to GPU, try the following:
device = torch.device('cuda:0' if torch.cuda.is_available() else 'cpu')

X_train=torch.FloatTensor(X_train).to(device)
X_test=torch.FloatTensor(X_test).to(device)
y_train=torch.LongTensor(y_train).to(device)
y_test=torch.LongTensor(y_test).to(device)
