This error was resolved when I modified the content of the workspace

new_local_repository(
    name = "python_system",
    build_file = "@//bazel:python.BUILD",
    path = "/home/haoo/anaconda3",
)

but when I run bazel test -c opt //python/tests:python_module_test a new error appeared

That looks like you haven't configured the build system for your local Python paths correctly. You may need to edit both WORKSPACE and python.BUILD. See https://github.com/deepmind/lab/blob/master/docs/users/build.md#python-dependencies for more information.

@tkoeppe thanks for answering! I have already edited both WORKSPACE and python.BUILD，the problem is actually that the paths of python2 and python3 are different, so the path in WORKSPACE cannot point to both at the same time. I edited the content in the python.BUILD and the problem was solved after deleting the part about python2.

[Thomas Köppe]

It is possible to configure both Py2 and Py3 at once, but if you don't need that, the your solution sounds fine.

Please reopen if there's anything else.
