ERROR: The project you're trying to build requires Bazel 3.7.2 (specified in /home/yongqiang/tensorflow_work/tensorflow/.bazelversion), but it wasn't found in /home/yongqiang/.bazel/bin.

Bazel binaries for all official releases can be downloaded from here:
  https://github.com/bazelbuild/bazel/releases

You can download the required version directly using this command:
  (cd "/home/yongqiang/.bazel/bin" && curl -fLO https://releases.bazel.build/3.7.2/release/bazel-3.7.2-linux-x86_64 && chmod +x bazel-3.7.2-linux-x86_64)

修改前：

(base) yongqiang@yongqiang:~/tensorflow_work/tensorflow$ cat .bazelversion
