The fisher_matrix is None in main.py?

[sty945]

An exciting work!! I noticed that in main.py, fisher_matrix=None (Line-263), and it is not used later.
How is the Fisher Information Matrix calculated in the program?

Hi, thanks for your question.

We use audio_trace_list, fim_trace_audio, visual_trace_list, fim_trace_visual to record the fim trace.
