WSL2でCUDAを使う

備忘録

参考：

やったこと

  • TPMを有効化 (BIOSで、Discrete TPM -> Firmware TPMに変更)
  • Windows 11 (Insider Preview)にアップグレード
  • 最新のドライバインストール
  • Ubuntu (20.04)にcuda-toolkit-11-4 のインストール

この時点で、こんな感じのエラーが出た。

$ ./deviceQuery
./deviceQuery Starting…

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

調べてみてもよくわからなかったが、

  • cudaのアップグレード
  • （ホスト）Windowsの再起動

をしたら直った。
