mat1 and mat2 shapes cannot be multiplied (64x9216 and 6400x4096)是什么意思

这个错误是在进行矩阵乘法时出现的。其中mat1的形状为(64, 9216)，mat2的形状为(6400, 4096)，这意味着这两个矩阵不能相乘。在矩阵乘法中，第一个矩阵的列数必须等于第二个矩阵的行数。在这个例子中，mat1的列数为9216，而mat2的行数为6400，它们不相等，因此无法相乘。你需要重新设计你的矩阵维度，使得它们可以相乘。

mat1 and mat2 shapes cannot be multiplied (64x9216 and 6400x4096)

The error message "mat1 and mat2 shapes cannot be multiplied (64x9216 and 6400x4096)" indicates that you are trying to perform matrix multiplication between two matrices that do not have compatible shapes. In matrix multiplication, the number of columns in the first matrix must equal the number of rows in the second matrix.

In your case, you have a matrix of size 64x9216 and a matrix of size 6400x4096. To perform matrix multiplication between these two matrices, the number of columns in the first matrix (9216) must equal the number of rows in the second matrix (6400), which is not the case here.

To fix this error, you need to either change the shape of one of the matrices or change your matrix multiplication operation.

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.
