Cannot use msccl-tools' xml

[Eevan-zq]

Why wasn't the method I generated using msccl-tools from the XML invoked when I executed the command ：

mpirun --allow-run-as-root -np 8 -x LD_LIBRARY_PATH=/home/msccl-tool/msccl/executor/msccl-executor-nccl/build/lib/:$LD_LIBRARY_PATH -x NCCL_DEBUG=INFO -x NCCL_DEBUG_SUBSYS=ALL /home/msccl-tool/msccl/tests/msccl-tests-nccl/build/all_reduce_perf -b 1 -e 32MB -f 2 -g 1 -n 100 -w 20 -z 0

and I check the code here: I find status.algoMetas.size() = 0 and then I trace here:

I find all .xml files that generated by msccl-tools don't containts minBytes, is this the reason why the algorithm included in the XML wasn't scheduled when I executed the mpirun command? If so, what should I do?

New msccl-tool fix this error.

by the way,
1： when I run this command:

the xml header is Why are minBytes and maxBytes equal to 0? Will it have any impact?

2： And the following will appear at the end of this XML file: This may be due to an error in the final Check validation in allreduce_a100_pcie_hierarchical.py：

I am currently unsure if the XML file generated by running python ./allreduce_a100_pcie_hierarchical.py --protocol=LL 8 1 > test.xml is correct？
