[Numpy-discussion] simple way to denote unchanged dimension in reshape?

[Chao YUE]

Dear all,

I have a simple question. Is there a way to denote the unchanged dimension
in the reshape function? like suppose I have an array named "arr" having
three dims with the first dimension length as 48, I want to reshape the
first dim into 12*4, but keeping all the other dimension length unchanged.

like when we slice the array, we can use:  arr[10:40, ... ], "...'
represents all remaining dimesions.

however when doing reshape, we must use:
arr.reshape(12,-1,arr.shape(1),arr.shape(2))

Is there something allowing more flexible reshape, like:
arr.reshape(12,-1,...)?

thanks a lot in advance,

best,

Chao
