Description

this is the stack trace:

analysis = tune.run(
  File "/home/ec2-user/pyvenv/lib64/python3.9/site-packages/flaml/tune/tune.py", line 536, in run
    search_alg = SearchAlgorithm(
  File "/home/ec2-user/pyvenv/lib64/python3.9/site-packages/flaml/tune/searcher/blendsearch.py", line 248, in __init__
    points_to_evaluate=self._evaluated_points,
AttributeError: 'BlendSearch' object has no attribute '_evaluated_points'

Contributor guide

Research direction
Identify where ` evaluated points` is assigned in blendsearch.py. Check if the assignment is within an assertion (e.g., `assert` statement). If it is, ensure the attribute is initialized before the assertion or outside of it so it works even with Python's ` O` flag.
