"ValueError: max() arg is an empty sequence" when trying to run via jupyterlab env

I'm trying to tokenflow via jupyterlab env.

On the last step, when running run_tokenflow_pnp.py, I get this error:

Traceback (most recent call last):

因为你没有先执行preprocess.py代码，导致路径os.path.join(self.latents_path, f'noisy_latents_*.pt')上的文件不存在。你应该先执行preprocess.py代码，再执行run_tokenflow_pnp.py。
