摘要:This is a mathematics book written specifically for the enjoyment of non-mathematicians and those who “hated math in school.” The book is organized into two sections: (I) Beauty for the Eye (shallow water for the non-swimmer); and
今天踩过的两个小坑:
一.用random的shuffle打乱数据集中的数据-标签对
index=[i for i in range(len(X_batch))]
# print(type(index))
index=random.shuffle(index)
结果shuffle完以后index变成None了,看了下api,这样说明的:
这个函数如果返回值,就返回None,所以用index=balabala就把index的内容改变了。去掉index=random.shuffle(index)等
