a bugs that occurred during the evaluation

When I used the model trained by the A2T attack to evaluate the robustness, the code used the other models to generate 1000 samples for evaluation.

Some of them, such as a2t and textflooer, can be run, but a2t-mlm and bae will get stuck at the normal point of generation. Stepping into debugging found that it was locked in the queue during parallel generation and caused the pause, but I don't know why it was locked, can you tell me why.

This looks like a real deadlock in the `--parallel` multiprocessing path, but a2t-mlm and bae both load a masked-LM (via `WordSwapMaskedLM`) that textfooler/a2t don't, so my first guess is contention or a hang during model loading/download inside a worker process rather than the queue mechanism itself. This needs an isolated repro to actually debug (a multiprocessing deadlock isn't something I can safely diagnose or fix blind from a screenshot). If you can reproduce with a minimal script (small dataset, `num_workers_per_device=1`) and share it, or note whether it also hangs without `--parallel`, that would help narrow down whether it's a real TextAttack bug or a specific model/environment interaction.
