something wrong with the last part of code

[brucelau126]

something wrong with the last part of code: I run the jupyter code, but there is something on my laptop. What's wrong with it? Thanks for your kindly help for a beginner ：） 结果显示如下，不知道哪里错了：

w1: [[-0.81131822 1.48459876 0.06532937] [-2.4427042 0.0992484 0.59122431]] w2: [[-0.81131822] [ 1.48459876] [ 0.06532937]]

感觉有可能是tf版本问题

重装了下 已调试成功，非常感谢
