torch.matmul 给出 RuntimeError
torch.matmul gives RuntimeError
我有两个张量
t1=torch.Size([400, 32, 400])
t2= torch.Size([400, 32, 32])
当我执行这个
torch.matmul(t1,t2)
我收到这个错误 RuntimeError:
Expected tensor to have size 400 at dimension 1, but got size 32 for
argument #2 'batch2' (while checking arguments for bmm)
任何帮助将不胜感激
你得到这个错误是因为矩阵乘法的顺序不对。
应该是：
a = torch.randn(400, 32, 400)
b = torch.randn(400, 32, 32)
out = torch.matmul(b, a) # You performed torch.matmul(a, b)
# You can also do a simpler version of the matrix multiplication using the below code
out = b @ a
