定义torch.cuda.LongTensor而不是torch.LongTensor

Question

当我运行以下代码时，变量类型变为torch.LongTensor。我如何才能让它创建一个torch.cuda.LongTensor呢？

# Turn string into list of longs
def char_tensor(string):
   tensor = torch.zeros(len(string)).long()
   for c in range(len(string)):          
      tensor[c] = all_characters.index(string[c])
   return Variable(tensor)

print(char_tensor('abcDEF'))

输出：

Variable containing:
 10
 11
 12
 39
 40
 41
[torch.LongTensor of size 6]

Answer 1

正确答案是：

# Turn string into list of longs
def char_tensor(string):
   tensor = torch.zeros(len(string)).long()
   for c in range(len(string)):          
      tensor[c] = all_characters.index(string[c])
   return Variable(tensor).cuda()

print(char_tensor('abcDEF'))
