ray installation broke with bazel 0.25.x

[fywu85]

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): 19.04
• Ray installed from (source or binary): source
• Ray version: latest
• Python version: 3.6
• Exact command to reproduce: pip install -e . --verbose

Describe the problem

pip install would fail with bazel version 0.25.x but bazel 0.24.1 works just fine. This is likely caused by census-instrumentation/opencensus-cpp#307

Thanks for reporting this, I'll take a look.

Disclaimer: I know nothing about C++, opencensus or abseil but making the following changes to ray/bazel/ray_deps_setup.bzl allowed me to build:

http_archive(
    name = "io_opencensus_cpp",
    #strip_prefix = "opencensus-cpp-v0.3.0",
    strip_prefix = "opencensus-cpp-master",
    #urls = ["https://github.com/census-instrumentation/opencensus-cpp/archive/v0.3.0.zip"],
    urls = ["https://github.com/census-instrumentation/opencensus-cpp/archive/master.zip"],
)

# OpenCensus depends on Abseil so we have to explicitly pull it in.
# This is how diamond dependencies are prevented.
