使用 Bazel 安装 Tensorflow 时调用了 ProcessError

Question

I am trying to install Tensorflow from source using Bazel on Raspberry pi. I am following the official documentation as given here . When I run the ./configure in Tensorflow directory after completing all the steps written for Bazel, I get the following error

/home/cvit/bin/bazel: line 88: /home/cvit/.bazel/bin/bazel-real: cannot execute binary file: Exec format error
/home/cvit/bin/bazel: line 88: /home/cvit/.bazel/bin/bazel-real: Success
Traceback (most recent call last):
  File "./configure.py", line 1552, in <module>
    main()
  File "./configure.py", line 1432, in main
    check_bazel_version('0.15.0')
  File "./configure.py", line 450, in check_bazel_version
    curr_version = run_shell(['bazel', '--batch', '--bazelrc=/dev/null', 'version'])
  File "./configure.py", line 141, in run_shell
    output = subprocess.check_output(cmd)
  File "/usr/lib/python2.7/subprocess.py", line 223, in check_output
    raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '['bazel', '--batch', '--bazelrc=/dev/null', 'version']' returned non-zero exit status 1

I didn't put the user flag in the bazel installation. So, I think this might be bazelrc error so I tried to set $PATH=$BAZEL/bin but nothing happened.

Please give any suggestion !!

Probably the problem is that the non appropriate version of bazel is installed. Run bazel version in the tensorflow directory, and see if there is an error. If there is a problem with bazel version, then check out the .baselversion file, and if it contains a version that isn't installable with apt, then dowload the installer from https://github.com/bazelbuild/bazel/releases then install it, else install with apt. After that everything should work fine.
