研究方向

The failing tests are in tests/sampling/test population.py. The error 'ValueError: setting an array element with a sequence' suggests a shape mismatch when constructing numpy arrays. Start by reproducing the issue locally with the same dependencies. Look at recent commits or dependency changes (e.g., numpy) that might have caused this. Inspect the test functions, particularly how population samples are generated, and ensure array inputs are properly shaped.
