I am a newbie in ML, after installing cuda 11.1 in my computer I have found a DLL error and fail to recognize my display card. I have searched different forum and found out that the error came from cusolver64_11.dll. So I used a older version cusolver64_10.dll and it seems to work well. But the loop time of my program with using cusolver64_10.dll is much slower than before. Did anyone can tell me that why would this happen, is this situation only happen when I use cusolver64_10.dll? Would it help if I change to use cusolver64_11.dll? How can I use cusolver64_11.dll again?
