Hi, I just got a very strange problem: I used the commands: “print(torch. **version** ) print(torch.version.cuda) print(torch.bac:sob:kends.cudnn.version())”, the output were: 0.4.1.post2 (PyTorch version) 9.0.176 (CUDA version) 7.1.2 (cuDNN version) I also used the “nvcc --version”, the results were: ![Capture4](https://discuss.pytorch.org/uploads/default/original/2X/8/8d9cc497380040f88798dfdfff4a0a63ded6a075.png) It was very strange, it seems that the CUDA version installed in Linux system is 9.0.176, and the CUDA that the PyTorch needed is also 9.0.176, but, the “cuda.is\_available()” still returns " **False**". Could anyone help me with this?😭 Many thanks! ## Environment - PyTorch Version (e.g., 1.0): 0.4.1.post2 - OS (e.g., Linux): Linux - Python version: 3.6.5 : : Anaconda, Inc. - CUDA/cuDNN version: 9.0.176 (CUDA version); 7.1.2 (cuDNN version) ---

Can you try PyTorch 1.0.0, i.e. the latest version of PyTorch? Also, is the nvidia driver the latest version on your machine? ---

Hi Smth, Many thansk for your help. As I am using the University’s HPC machine-I don’t have permission to install any software unless report this issue to staff and they may update it after Christmas holiday.😭 In addition, I also use "nvidia-smi’ command to check the NVIDIA driver version, however, it shown: command not found… I am not sure the version of NVIDIA driver. May I ask if this issue mainly caused by the incompatible versions? Thanks. ---

One solution is to try the CUDA8 version of PyTorch that you can install by selecting it from [https://pytorch.org](https://pytorch.org) `torch.cuda.is_available()` can return false if you dont have a new enough NVIDIA driver that your CUDA version needs. ---

Hi Smth, Many thanks for your help. I will try it.🙂 ---

really helped a lot! after upgrading to the latest NVIDIA driver, torch.cuda.is\_available() returns True!
