```

请教一下这个错误的原因大概是什么呢？
另外感觉奇怪的是为什么euler依赖的python2.7呢？未来会考虑迁移到python3吗？
Docker版本：Docker version 18.06.1-ce, build e68fc7a
在下载依赖时报了libFuzzer下载失败，有替代的可用吗？
```
git submodule update --init --recursive

```

Start with tools/docker/Dockerfile and tools/docker/pip.conf, then reproduce the command shown in the issue and inspect the failure at step 14 while installing TensorFlow. Determine the build dependency or environment problem from the complete output; done means the Docker image builds successfully with the documented command.
