dlerror: cudart64_101.dll not found  (1) 2021.08.01 
W tensorflow/stream_executor/platform/default/dso_loader.cc:59] Could not load dynamic library 'cudart64_101.dll'; dlerror: cudart64_101.dll not found

cuda가 정상적으로 설치 되었음에도 cudart64_101.dll이 없다며 에러가 발생하곤 한다.


nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Wed_Oct_23_19:32:27_Pacific_Daylight_Time_2019
Cuda compilation tools, release 10.2, V10.2.89

심지어 10.2 버전의 cuda를 설치했음에도 cudart64_101.dll 즉 10.1 버전의 dll을 요구한다.


이를 위한 간단한 해결법을 기록해 놓는다.

cuda가 설치된 폴더로 들어가서, cudart64_102.dll 파일을 복사해서 cudart64_101.dll로 저장한다.

  • 윈도우의 경우 C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\bin 에서 확인할 수 있다.
