python重塑-平面化时获得不同的结果

Question

下面的两个命令不应该返回相同的结果吗？但在下面的情况下，我得到了不同的results...what，我错过了吗？

A trick when you want to flatten a matrix X of shape (a,b,c,d) to a matrix X_flatten of shape (b ∗∗ c ∗∗ d, a) is to use:


X_flatten = X.reshape(X.shape[0], -1).T      
train_set_x_flatten = train_set_x_orig.reshape(train_set_x_orig.shape[1]*train_set_x_orig.shape[2]*train_set_x_orig.shape[3],train_set_x_orig.shape[0] )

Answer 1

这只是一个汉化的问题。缺少括号

试试这个：

train_set_x_flatten = train_set_x_orig.reshape((train_set_x_orig.shape[1]*train_set_x_orig.shape[2]
* train_set_x_orig.shape[3], train_set_x_orig.shape[0]))
