Bazel: no such package '@protobuf//': java.io.IOException: Error downloading ... Checksum was XXX but wanted YYY

[OleksandrMalinin]

Description of the problem / feature request / question:

Whole day "bazel build" command fails. From logs I see that it compares check sum '@protobuf//' and they do not match. I've tried it on several machines - had same error.

If possible, provide a minimal example to reproduce the problem:

git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
./configure
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package

Environment info

• Operating System: Ubuntu 16.04

• Bazel version (output of bazel info release): release 0.5.2 (also tried 0.5.3, 0.5.4 - had same result)

Anything else, information or logs or outputs that would be helpful?

Hey -- take a look at https://github.com/tensorflow/tensorflow/issues/12979 ... it seems GitHub changed the way they compress archives and invalidated all the existing checksums. :(

[OleksandrMalinin]

Hi, @davidstanke ,
Thank you very much for response. I will monitor that issue :)

Got same issue, also solved by editing "tensorflow/workspace.bzl"

[100cm]

@BIG-CHENG how to edit it?

[alexanderremm]

@100cm
I was able to get this to work by editing two files: third_party/repo.bzl and tensorflow/workspace.bzl
This assumes that you need to add a local repository due to network restrictions.

Add this to the bottom of your repo.bzl:

def _tf_local_repository(ctx):
    ctx.symlink(ctx.attr.path, "")

tf_local_repository = repository_rule(
    implementation=_tf_local_repository,
    local=True,
    attrs={"path": attr.string(mandatory=True)})

Add this to the top of your workspace.bzl

load("//third_party:repo.bzl", "tf_local_repository")

Finally, in the workspace.bzl, change both of the tf_http_archive to this (change PATH_TO_PROTOBUF to path of the archive on your machine):

tf_local_repository(
        name = "protobuf_archive",
        path = "PATH_TO_PROTOBUF",
    )

    # We need to import the protobuf library under the names com_google_protobuf
    # and com_google_protobuf_cc to enable proto_library support in bazel.
    # Unfortunately there is no way to alias http_archives at the moment.
    tf_local_repository(
        name = "com_google_protobuf",
        path = "PATH_TO_PROTOBUF",
    )

This also allows you to import any local repositories into the workspace.bzl now.

@alexanderremm I tried this and ran into an error about protobuf.bzl not having the @protobuf_archive// package - do you know why this might be happening?

ERROR: error loading package 'tensorflow': Encountered error while reading extension file 'protobuf.bzl': no such package '@protobuf_archive//': tf_local_repository rule //external:protobuf_archive must create a directory

[alexanderremm]

@nkjassal I am not sure why your protobuf.bzl is giving you an error. Double check the path to the archive. Mine ended up being something like this.

tf_local_repository(
        name = "protobuf_archive",
        path = "C:/bazel/repos/protobuf-3.6.0",
    )

    # We need to import the protobuf library under the names com_google_protobuf
    # and com_google_protobuf_cc to enable proto_library support in bazel.
    # Unfortunately there is no way to alias http_archives at the moment.
    tf_local_repository(
        name = "com_google_protobuf",
        path = "C:/bazel/repos/protobuf-3.6.0",
    )

The path should point to the directory of the BUILD file.
Let me know if you are still having issues.
