3. 安裝CUDA
- 開始安裝
$ sh cuda_8.0.61_375.26_linux.run
# accept
-------------------------------------------------------------
Do you accept the previously read EULA?
accept/decline/quit: accept
# no
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 375.26?
(y)es/(n)o/(q)uit: n
-------------------------------------------------------------
# 后面的就都選yes或者default
Do you want to install the OpenGL libraries?
(y)es/(n)o/(q)uit [ default is yes ]:
Do you want to run nvidia-xconfig?
This will update the system X configuration file so that the NVIDIA X driver
is used. The pre-existing X configuration file will be backed up.
This option should not be used on systems that require a custom
X configuration, such as systems with multiple GPU vendors.
(y)es/(n)o/(q)uit [ default is no ]: y
Install the CUDA 8.0 Toolkit?
(y)es/(n)o/(q)uit: y
Enter Toolkit Location
[ default is /usr/local/cuda-8.0 ]:
Do you want to install a symbolic link at /usr/local/cuda?
(y)es/(n)o/(q)uit: y
Install the CUDA 8.0 Samples?
(y)es/(n)o/(q)uit: y
Enter CUDA Samples Location
[ default is /root ]:
Installing the NVIDIA display driver...
The driver installation has failed due to an unknown error. Please consult the driver installation log located at /var/log/nvidia-installer.log.
===========
= Summary =
===========
Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-8.0
Samples: Installed in /root, but missing recommended libraries
Please make sure that
- PATH includes /usr/local/cuda-8.0/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-8.0/lib64, or, add /usr/local/cuda-8.0/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-8.0/bin
Please see CUDA_Installation_Guide_Linux.pdf in /usr/local/cuda-8.0/doc/pdf for detailed information on setting up CUDA.
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 361.00 is required for CUDA 8.0 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
sudo <CudaInstaller>.run -silent -driver

- 驗(yàn)證安裝結(jié)果
# 添加環(huán)境變量
# 在 ~/.bashrc的最后面添加下面兩行

4. 安裝 cuDNN 庫
$ tar -xvzf cudnn-8.0-linux-x64-v6.0.tgz
$ cp -P cuda/include/cudnn.h /usr/local/cuda-8.0/include
$ cp -P cuda/lib64/libcudnn* /usr/local/cuda-8.0/lib64
$ chmod a+r /usr/local/cuda-8.0/include/cudnn.h /usr/local/cuda-8.0/lib64/libcudnn*
5. 在 Docker 中使用 cuda
下面介紹了如何在docker中使用cuda粥诫，主要使用了nvidia-docker
- 安裝docker
$ yum install docker
# 啟動(dòng) Docker 服務(wù)，并將其設(shè)置為開機(jī)啟動(dòng)
$ systemctl start docker.service
$ systemctl enable docker.service
# 1. Install nvidia-docker and nvidia-docker-plugin
$ wget -P /tmp https://github.com/NVIDIA/nvidia-docker/releases/download/v1.0.1/nvidia-docker-1.0.1-1.x86_64.rpm
$ sudo rpm -i /tmp/nvidia-docker*.rpm && rm /tmp/nvidia-docker*.rpm
$ sudo systemctl start nvidia-docker
# 2. 使用nvidia-docker啟動(dòng)容器
$ nvidia-docker run -it --name=CONTAINER_NAME -d DOCKER_IMAGE_NAME /bin/bash
# 3. 進(jìn)入容器
$ docker attach CONTAINER_NAME
注意
2 使用nvidia-docker啟動(dòng)容器
這里需要對(duì)image進(jìn)行重新編譯蒙畴，添加nvidia-docker需要的Label酪耕，否則運(yùn)行起來的容器會(huì)不能使用GPU。
6. TensorFlow 的 GPU 使用
下載安裝GPU版本的TensorFlow滓彰，運(yùn)行以下代碼即可測(cè)試控妻，無報(bào)錯(cuò)說明cuda安裝成功
import tensorflow as tf
# 新建一個(gè) graph.
a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
c = tf.matmul(a, b)
# 新建session with log_device_placement并設(shè)置為True.
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
# 運(yùn)行這個(gè) op.
print sess.run(c)
7. Openface 的 GPU 使用
# 啟動(dòng)編譯好的 openface 鏡像 chinapnr/openface:0.3
$ nvidia-docker run -it -v /local-folder/:/root/openface_file/ --name=openface -d chinapnr/openface:0.3 /bin/bash
# 進(jìn)入容器
$ docker exec -it openface /bin/bash
# 訓(xùn)練模型
$ cd /root/openface/training
$ ./main.lua -data /root/cuda-base/openface/CASPEAL-align-folder/ -device 1 -nGPU 1 -testing -alpha 0.2 -nEpochs 100 -epochSize 160 -peoplePerBatch 35 -imagesPerPerson 20 -retrain /root/openface/models/openface/nn4.small2.v1.t7 -modelDef /root/openface/models/openface/nn4.small2.def.lua -cache ../../cuda-base/openface/work
