问题记录 | deepin15.10重装nvidia驱动及cuda
2024-09-06 09:59:43
问题描述：
nvidia-smi也有显示，显卡驱动是在的，而且nvcc显示出来的cuda版本9.0也没错，不是9.1。不知道问题所在，索性重装全部。
sudo tee /proc/acpi/bbswitch <<<ON
# ON
nvidia-smi
显示如下：

nvcc --version
显示如下：
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
显示如下：
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M] (rev a2)
检查pytorch调用cuda是否正常：
python -c 'import torch; print(torch.cuda.is_available())'
显示如下：
False
卸载cuda
sudo /usr/local/cuda-9.0/bin/uninstall_cuda_9.0.pl
#这里之后只剩下cudnn的东西，也可以完全删了。
sudo rm -rf /usr/local/cuda-9.0/
卸载nvidia驱动及大黄蜂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
安装显卡驱动和大黄蜂bumblebee
sudo apt-get install nvidia-smi
sudo apt-get install bumblebee-nvidia nvidia-driver nvidia-settings
安装显卡驱动测试程序
sudo apt-get install mesa-utils
显示N卡相关信息：
optirun glxinfo|grep NVIDIA
运行测试程序
optirun glxgears -info
成功调用显卡驱动，信息如下：
GL_RENDERER = GeForce GTX 950M/PCIe/SSE2
GL_VERSION = 4.6.0 NVIDIA 390.67
GL_VENDOR = NVIDIA Corporation
安装cuda
sudo ./cuda_9.0.176_384.81_linux.run
安装过程只有这个选no
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 384.81?
(y)es/(n)o/(q)uit: n
下载安装cudnn
<https://developer.nvidia.com/rdp/cudnn-archive>
登录下载对应版本我是选择了
cudnn-9.0-linux-x64-v7.5.0.56
这个版本的
把对应的额外的cudnn库放入cuda对应的位置：
sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/* /usr/local/cuda/include/
然后检查环境变量并开启默认N卡
# 检查LD_LIABRARY_PATH和PATH
sudo vim ~/.bashrc
# 用大黄蜂开启默认N卡
sudo tee /proc/acpi/bbswitch<<<ON
再次检查pytorch是否能调用cuda
python -c "import torch;print(torch.cuda.is_available())"
显示如下：
True
检查tensorflow是否正常调用gpu
python3 -c "import tensorflow as tf;print(tf.test.is_gpu_available());print(tf.test.gpu_device_name())"
显示如下：
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，没有比我这更复杂了吧，卸了重装，有卸载过程和安装过程。
