question about ”d2l = sys.modules[__name__]“

[lprdsb]

I want to know why in d2l.torch there is this line of code: d2l = sys.modules[name], which causes my IDE to not correctly recognize some functions inside torch. When I try to view the source code, it doesn't jump to the correct location. However, I believe there might be another purpose for writing it this way, and I want to understand the benefits of doing so.
