inference output

When I used src/test/inference.py to generate cad sequence output, I got this:

The output looks like uncorrect. What is this problem? Thank you!

Start by running src/test/inference.py and compare the generated output with the ground_truth CAD command sequence shown in the issue. Trace where the malformed output is produced and determine what correction is needed; done means inference returns a valid CAD command sequence for the supplied description.
