how to debug cuda code

[AceCoooool]

hi, @goldsborough , Is there a good way to debug .cu code ?
From your great tutorial, I write a extension of ROI Align&ROI Pool. The cpp code is pretty easy to debug (just as the pure c++ code), however, i find it "troublesome" to debug of the cuda code (run python setup.py install again and again), and nvcc will raise error about cannot find ATen library.

Would you have any advice for debug cuda code?

Thank you !
(I find there are little discussions about c++ extension in Forums, so i pull an issue here. )

Thanks for response, I did not find error yet. ~ I just curious about how to debug cuda code efficiently (Maybe it's inappropriate to discuss this topic here). I will close this issue. However, if anyone have good advice, can share it~ 😄

Hi, do you find an efficient way to debug cuda code now?
