Hi Cheng,
Given that you are getting an error code that is no longer in your edited source code, it looks as though your changes have not been implemented.
Some possible thoughts, as to why:
1. You mention building and testing, but not running scons install. If you have truly skipped this, you might try running that first.
2. Are you perhaps coupling inside a virtual environment (via condo, for example), but not running from within this environment?
3. A good first step, regardless, would be to write some test coverage of your new lines. That way running icons test would provide an initial verification that your fix worked. If the test passes but your code still hits an error, that might
give us some clues.
Best,
Steven
