Ich habe ein Problem bei der Installation von Cutorch mit Luarocks. Der Fehler kündigt an, dass die GPU-Architektur 'compute_61' nicht unterstützt wird. Nach einiger Suche habe ich herausgefunden, dass das Problem durch alte CUDA-Version verursacht werden kann. Aber es ist nicht der Fall, da ich CUDA 8,0nvcc fatal: Nicht unterstützte GPU-Architektur 'compute_61', während CUDA 8.0 installiert ist

, was das Problem sein könnte ?
Die cmake-Ausgabe weist auf eine Cuda 7.5-Installation auf Ihrem Computer hin. Sie können versuchen, es zu aktualisieren, oder bearbeiten Sie das Makefile, um Cuda 8.0 zu verwenden, oder bearbeiten Sie die Umgebungsvariable, die auf Cuda 7.5 verweist (falls vorhanden). – Rakete1111
