Reason for error
When I processed the data in jupyter, the for loop wrote too much and the data was printed too much, which caused the ipython file to be too large, and then I tried many ways to open it but failed.
Solution
Just open it with a compiler that supports ipython, hahaha, I installed VsCode for this purpose and opened it directly, probably because the web version can't support that much memory. Copy the code now!
Hahaha! Scared me.
