【ERROR】TypeError: expected bytes, Descriptor found

起因：

帮我可爱的妹子在windows电脑上，尝试跑通一个tensorflow的GAN代码

 

报错信息：

TypeError: expected bytes, Descriptor found

 

出错位置：

TypeError: expected bytes, Descriptor found

 

分析：

从 __module__ = 'tensorflow.core.framework.tensor_shape_pb2 可以看到tensorflow系统文件出错

 

初步怀疑是tensorflow版本和电脑不匹配，所以尝试了多个版本tensorflow的安装：

使用代码可以查看版本：conda search --full-name tensorflow

tensorflow== (from versions: 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0, 1.7.1, 1.8.0rc0, 1.8.0rc1, 1.8.0, 1.9.0rc0, 1.9.0rc1, 1.9.0rc2, 1.9.0, 1.10.0rc0, 1.10.0rc1, 1.10.0, 1.11.0rc0, 1.11.0rc1, 1.11.0rc2, 1.11.0, 1.12.0rc0, 1.12.0rc1, 1.12.0rc2, 1.12.0, 1.12.2, 1.12.3, 1.13.0rc0, 1.13.0rc1, 1.13.0rc2, 1.13.1, 1.13.2, 1.14.0rc0, 1.14.0rc1, 1.14.0, 1.15.0rc0, 1.15.0rc1, 1.15.0rc2, 1.15.0rc3, 1.15.0, 2.0.0a0, 2.0.0b0, 2.0.0b1, 2.0.0rc0, 2.0.0rc1, 2.0.0rc2, 2.0.0, 2.1.0rc0)

pip install tensorflow
conda install tensorflow
各种试
命令自己给安了很多库，包括并不限于bleach tensorflow-tensorboard 等等

错误终于变成了：

>>> import tensorflow as tf
Traceback (most recent call last):

    __module__ = 'google.protobuf.descriptor_pb2'
TypeError: expected bytes, Descriptor found

 

分析：

从__module__ = 'google.protobuf.descriptor_pb2'可以看出，错误是protobuf的问题。

本环境是python3，所以怀疑是1.protobuf版本过低,2.protobuf支持py2,需要装py3。所以：

pip install protobuf-py3
pip install --upgrade protobuf

 

重新运行，发现错误变化，说明上一个问题已解决，下一个环境有问题。。。（吐血）

查博客，查到：

pip install  pandas==0.23.0

 

再次重新检查

>>> import tensorflow
>>> hello = tensorflow.constant('helllllllllo')
>>> sess = tf.session()
>>> sess = tensorflow.Session()
>>> print(sess.run(hello))
b'helllllllllo'

终于成功。。。

普天同庆！！！

 

心得：

人生苦短，我用Pytorch。。。tensorflow路转黑（哭泣）
