踩坑

通用

python 运行报错SyntaxError: Non-ASCII character

SyntaxError: Non-ASCII character '\xe6' in file xxx.py on line xxx, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

在文件头上加上# encoding: utf-8即可

exp4

exp4.4 bazel 报错corrupt installation

错误信息如：

$ bazel version
FATAL: corrupt installation: file '/<workspace>/.cache/bazel/_bazel_root/install/<hash>/A-server.jar' is missing or modified. Please remove '/<workspace>/.cache/bazel/_bazel_root/install/<hash>' and try again.

简单的解决方法是删除缓存文件后重新运行

$ sudo rm -rf /<workspace>/.cache/bazel/_bazel_root/install/<hash>
$ bazel version

需要注意将<workspace>和<hash>换成自己的目录

或者可以重新安装 bazel，参考官方文档

$ wget https://releases.bazel.build/0.24.0/rc9/bazel-0.24.0rc9-installer-linux-x86_64.sh
...
$ chmod +x bazel-0.24.0rc9-installer-linux-x86_64.sh
$ ./bazel-0.24.0rc9-installer-linux-x86_64.sh
...
$ export PATH=/usr/local/bin:$PATH
$ bazel version
Build label: 0.24.0rc9
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Thu Mar 21 19:49:51 2019 (1553197791)
Build timestamp: 1553197791
Build timestamp as int: 1553197791

需要注意安装的版本应在0.24.0到0.25，过旧或过新的版本无法编译课程使用的 tensorflow 版本

exp4.4 tensorflow 编译时报错server terminated abruptly

修改编译脚本build_tensorflow-v1.10_mlu.sh，将jobs_num从 32 改为 16 即可（更小理论可行，但编译速度会慢；更大未经测试）

$ vi build_tensorflow-v1.10_mlu.sh
...
jobs_num=32 // 改为 jobs_num=16
...
