tool-test failed

Hi, there. I v just dived into this package, and i m trapped into an error while running python3 -m unittest test_nn_dataflow_search.py without any change in the repo. I am wondering why these 3 tests all failed. What should i do to solve this for further application? Thanks a lot.

ERROR is described as below.
