Test_slbs.py test failed

I tested the two sample codes you provided (slbs and lbc) separately, and both failed and reported an error indicating that the corresponding module was not imported, as shown below:

I followed your tutorial step by step to configure the environment, but no matter if I use py38 or py39 or py310, the result is always the same. It's really a bit disturbing, so I'd appreciate it if you could point out what I might have missed!
