这里面大家需要注意的是: 采用在终端输入 ubuntu-drivers devices
会提示推荐你用什么版本,我的设备显示不出来,所以安装的是418.43这个型号的驱动。(目前最新版本)
注意事项一:官网下载地址
推荐网址:(https://www.geforce.cn/drivers)只有这个GeForce型号的,别的型号推荐去其对应的网址查询。
注意事项二:不要在下面这个网址下载,不是不能,最直接的官网,对应的东西最新,也最详细
网址如下(https://www.nvidia.com/Download/index.aspx?lang=cn)
理由:
- (1)上面的网址,选择驱动型号,点进去可以看到许多详细的信息,尤其是它支持什么样的显卡,都有,特别详细。
- (2)这个网址在我写博客(2019.3.6)为止,还没有GTX1660Ti的Ubuntu驱动
注意事项三:具体操作见网上别人写好的。
2.安装 CUDA 1.0 + cuDNN 7
CUDA
下面这个网址是tensorflow各环境参数对应版本图(https://tensorflow.google.cn/install/source)可供参考。cuda和cudnn对应关系应该没问题,但是tensorflow版本不能过高,否则会出错。
注意事项一:下载地址
cuda下载网址为:(https://developer.nvidia.com/),右上角搜索“CUDA Toolkit Archive”,点击第一个(最新的)的进去,里面有许多版本可供选择,切记!切记!切记!目前网友的说法是:tensorflow只能支持cuda9.0及以下版本。
注意事项二:选择run下载,而不选择del
这个具体是什么原因,没搞明白,网友也强烈推荐run,我之前试过del的,失败了,所以大家尽量采用run这种方法。可能有人没明白说明意思,你在选择的时候多留个心眼就注意到了。
cuDNN
官网网址如下
网址:https://developer.nvidia.com/cudnn
需要注册,我是从别人那直接过来的,就没注册,大家需要的自己去,这个安装相对简单。
同样有验证的过程,这个相对来说是简单的,没什么需要太注意的,跟着网上的走就好了。
执行命令
$ sudo apt-get install gnupg-curl
$ wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_10.0.130-1_amd64.deb
$ sudo dpkg -i cuda-repo-ubuntu1604_10.0.130-1_amd64.deb
$ sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
$ sudo apt-get update -y
# sudo apt-get install cuda
$ sudo apt-get install --no-install-recommends \
cuda-10-0 \
libcudnn7=7.6.2.24-1+cuda10.0 \
libcudnn7-dev=7.6.2.24-1+cuda10.0
$ sudo apt-get install -y --no-install-recommends libnvinfer5=5.1.5-1+cuda10.0 libnvinfer-dev=5.1.5-1+cuda10.0
3.安装TensorFlow并验证
- GPU安装:
sudo pip3 install tensorflow-gpu
from __future__ import absolute_import, division, print_function, unicode_literals
import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))
结果:
>>> from __future__ import absolute_import, division, print_function, unicode_literals
>>>
>>> import tensorflow as tf
>>> print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))
