安裝torch出現如下錯誤make[2]: *** [lib/THC/CMakeFiles/THC.dir/THC_generated_THCTensorMath.cu.o] Error 1 CMak
torch安裝地址
按照官網步驟
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch
bash install-deps
./install.sh依賴保證安裝完畢以後
執行最後一步後出現錯誤如下：

此時嘗試採用如下命令進行安裝：
sudo su
export TORCH_NVCC_FLAGS="-D__CUDA_NO_HALF_OPERATORS__"
bash install-deps
yes | bash ./install.sh按照此方法，對我來講是有效的，已經成功安裝torch
