Error when running the unit test

[youhonghui]

Hello!
I aimed to reproduce the environment for the paper nGraph-HE.
I used Ubuntu 18.04 on WSL.
Bazel is set to 0.16.0.
I successfully installed the he-transformer-0.2-benchmarks-2 step by step according to the instructions in Readme.

I succeeded in the CKKS and BFV unit-tests, but I got the following error when I run all the unit tests with the command ./test/unit-test.
