标签：矩阵 api cti from can atm bsp execution odi 调用该API可以不通过 tensorflow.Session.run()调用 定义的张量constant tensor,可以直接print tensorflow-eagerAPI 标签：矩阵 api cti from can atm bsp execution odi 原文地址：https://www.cnblogs.com/tangpg/p/9132304.html# -*- coding: utf-8 -*-

print(a.shape[0]) # 多少组维度信息
print(a.shape[1]) # 维度
# tensor对象能够迭代? range ?????
for i in range(a.shape[0]):
for u in range(a.shape[1]):
