Auto-Configuration Error when run Bazel
zczlsde opened this issue · 3 comments
When I run the bazel run -c opt :print_names_and_sources /tmp/dm-code_contests/code_contests_valid.riegeli, an error occurred.
ERROR: An error occurred during the fetch of repository 'local_config_cc':

Could anyone help me to resolve this?
It looks like you don't have a C++ compiler available. I would try installing clang, and then making sure it's in your PATH with which clang.
Thanks a lot! It solves my problem. By the way, how to use this dataset for training. I could only view the question name through the command bazel run -c opt :print_names_and_sources /tmp/dm-code_contests/code_contests_valid.riegeli but how to view the contents and feed the dataset to my model. Are there any guides for this?
If you look at the source code for print_names_and_sources.py, you should be able to see how the name is printed from the contest problem protobuf.
You can see the rest of the protobuf format in contest_problem.proto.
If you're not familiar with how to work with protobufs, I would start here: https://developers.google.com/protocol-buffers/docs/pythontutorial
