deepin15.10重灌nvidia驅動及cuda

ManWingloeng發表於2019-05-28

問題描述：

nvidia-smi也有顯示，顯示卡驅動是在的，而且nvcc顯示出來的cuda版本9.0也沒錯，不是9.1。不知道問題所在，索性重灌全部。

sudo tee /proc/acpi/bbswitch <<<ON
# ON
nvidia-smi

顯示如下：

nvcc --version

顯示如下：

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Sep__1_21:08:03_CDT_2017
Cuda compilation tools, release 9.0, V9.0.176
lspci | grep -i nvidia

顯示如下：

01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M] (rev a2)

檢查pytorch呼叫cuda是否正常：

python -c 'import torch; print(torch.cuda.is_available())'

顯示如下：

False

解除安裝cuda

sudo /usr/local/cuda-9.0/bin/uninstall_cuda_9.0.pl  
#這裡之後只剩下cudnn的東西，也可以完全刪了。
sudo rm -rf /usr/local/cuda-9.0/

解除安裝nvidia驅動及大黃蜂bunmblebee

sudo apt-get remove --purge nvidia-cuda-dev nvidia-cuda-toolkit nvidia-nsight nvidia-visual-profiler
sudo apt autoremove --purge bumblebee-nvidia nvidia-driver nvidia-settings

安裝顯示卡驅動和大黃蜂bumblebee

sudo apt-get install nvidia-smi
sudo apt-get install bumblebee-nvidia nvidia-driver nvidia-settings

安裝顯示卡驅動測試程式

sudo apt-get install mesa-utils

顯示N卡相關資訊：

optirun glxinfo|grep NVIDIA

執行測試程式

optirun glxgears -info

成功呼叫顯示卡驅動，資訊如下：

GL_RENDERER   = GeForce GTX 950M/PCIe/SSE2
GL_VERSION    = 4.6.0 NVIDIA 390.67
GL_VENDOR     = NVIDIA Corporation

安裝cuda

https://developer.nvidia.com/cuda-90-download-archive?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604&target_type=runfilelocal
下載runfile

sudo ./cuda_9.0.176_384.81_linux.run

安裝過程只有這個選no

Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?
(y)es/(n)o/(q)uit: n

下載安裝cudnn

<https://developer.nvidia.com/rdp/cudnn-archive>

登入下載對應版本我是選擇了

cudnn-9.0-linux-x64-v7.5.0.56

這個版本的

把對應的額外的cudnn庫放入cuda對應的位置：

sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/* /usr/local/cuda/include/

然後檢查環境變數並開啟預設N卡

# 檢查LD_LIABRARY_PATH和PATH
sudo vim ~/.bashrc

# 用大黃蜂開啟預設N卡
sudo tee /proc/acpi/bbswitch<<<ON

再次檢查pytorch是否能呼叫cuda

python -c "import torch;print(torch.cuda.is_available())"

顯示如下：

True

檢查tensorflow是否正常呼叫gpu

python3 -c "import tensorflow as tf;print(tf.test.is_gpu_available());print(tf.test.gpu_device_name())"

顯示如下：

2019-05-28 22:52:25.862539: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA

都正常了，沒有比我這更復雜了吧，卸了重灌，有解除安裝過程和安裝過程。
