这个错误是由于矩阵 mat1 和 mat2 的形状不兼容,无法进行矩阵乘法运算所导致的。具体来说,mat1 的形状是 2x4096,mat2 的形状是 1024x4096,两个矩阵的列数不一致,因此无法进行矩阵乘法运算。要解决这个问题,你需要调整矩阵的形状,使得它们可以相乘。你可以使用 numpy 库的 reshape() 方法来改变矩阵的形状,或者使用 transpose() 方法来转置矩阵。

RuntimeError: mat1 and mat2 shapes cannot be multiplied (64x64 and 4096x4096)
This error occurs when attempting to perform matrix multiplication between two matrices with incompatible shapes. Specifically, the number of columns in the first matrix (mat1) must match the number of rows in the second matrix (mat2) in order for the multiplication to be valid.
In this case, mat1 has dimensions 64x64 and mat2 has dimensions 4096x4096. Since the number of columns in mat1 is not equal to the number of rows in mat2, it is not possible to perform matrix multiplication between these two matrices.
To resolve this error, either modify the dimensions of the matrices so that they are compatible for multiplication (i.e. the number of columns in mat1 matches the number of rows in mat2), or use a different operation that is compatible with the current dimensions of the matrices.
RuntimeError: mat1 and mat2 shapes cannot be multiplied (1x65536 and 1024x64)
这个错误提示说明你正在尝试用PyTorch进行矩阵乘法运算,但是输入的两个矩阵的形状不匹配,无法进行乘法运算。具体来说,mat1的形状是(1, 65536),mat2的形状是(1024, 64),这两个矩阵的行列数不满足矩阵乘法的规则,因此无法相乘。要解决这个问题,你需要重新检查你的代码,确保输入的矩阵形状符合你的预期。
