• So

  session = isf.InspireFaceSession(
  -   opt=isf.HF_ENABLE_NONE,  # Optional features
  +   param=isf.HF_ENABLE_NONE,  # Optional features
      detect_mode=isf.HF_DETECT_MODE_ALWAYS_DETECT  # Detection mode
  )

PR Summary:

• Fixes a typo in python/README.md where the keyword argument opt= was incorrectly documented for isf.InspireFaceSession()
• The correct parameter name is param=, matching the actual __init__ signature in inspireface.py
• Caused a TypeError for anyone who copied the README example verbatim

Review Summary:

The change is correct and well-targeted. Verified against InspireFaceSession.__init__() (line 301 of python/inspireface/modules/inspireface.py), which clearly defines param as the first positional argument — not opt. The fix is minimal, accurate, and resolves a real user-facing error reproduced in the PR description. No other occurrences of opt= were found in sample files. No issues identified.

Suggestions

• Search the entire codebase for any other README or sample files that might still reference the old opt= argument pattern. Apply
• Add a brief docstring or inline comment in the README clarifying that param accepts either an int flag (e.g. HF_ENABLE_NONE) or a SessionCustomParameter object. Apply
