For a matrix with n rows and m columns, shape will be (n,m). The length of the shape tuple is therefore the number of axes, ndim. 数组的维度。它的返回值是一个元组,这个元组描述了每个维度中数组的大小。相对于一个矩阵来说,shape表示的就是n行m列。这个元组的长度,等价于轴/维度的个数,即...

Hi, I have a matrix A_{mxn}. For each column, I would like to split all the rows into a sxt matrix such that the final matrix looks like B_{{sxt}xn}. Is there a way I can do matrix operations with reshape. A loop is computationally too expensive for large A. ...

When performing linear (matrix multiplication) operator under bf16 on A100, if one dimension length is an odd number (I tried 3,5,101), the speed is 136x~283x slower than those of nearest even number dimension sizes. eg, for the following code python reproduction_code.py bf16 3 cost ...
