When I run python oss_coverage.py --run-only=test_complex.py, I get a Warning pytorch/tools/code_coverage/package/util/../../profile/raw/test_complex.py.profraw: unsupported instrumentation profile format version and a Error error: no profile can be merged
The results as follows:
(pytorchcov) myconda@.. code_coverage % python oss_coverage.py --run-only=test_complex.py

After reading the Error, I run llvm-profdata merge -sparse /Users/../pytorch/tools/code_coverage/package/util/../../profile/raw/test_complex.py.profraw -o /Users/../pytorch/tools/code_coverage/package/util/../../profile/merged/test_complex.py.merged
I get

error: no profile can be merged
I would like to know what causes this problem and how to fix it.
