提示: 若事先没有驱动,或者有但不适合3090显卡,一种方法是先不装3090,安装驱动,另一种是装上3090安装,但是后者会提示如下错误

在这里插入图片描述

此时,按 Ctrl+Alt+F2切换到命令行模式,注意不要按Ctrl+Alt+F1,否则用 sudo service lightdm stop 可能不能完全关闭 Xserver, 然后安装显示驱动时会报如下错误

在这里插入图片描述

仅安装显示驱动

可以通过下载的cudatoolkit安装包安装(如 cuda_11.1.0_455.23.05_linux.run), 也可以单独下载显示驱动文件安装(如 NVIDIA-Linux-x86_64-455.45.01.run)

在这里插入图片描述

 ERROR: You appear to be running an X server; please exit X before installing.  For 
         further details, please see the section INSTALLING THE NVIDIA DRIVER in the 
         README available on the Linux driver download page at www.nvidia.com.

提示没有完全关闭 Xserver. 使用 ps aux | grep X 查看, 确实可以发现相关进程, 如果用 sudo service lightdm stop 或 sudo /etc/init.d/lightdm stop 或 sudo /etc/init.d/gdm stop (如果是gdm桌面) 不能完全关闭 Xserver, 在刚开机快进入桌面, 弹出驱动错误对话框时, 按 Ctrl+Alt+F2切换到命令行模式,注意不要按Ctrl+Alt+F1. 然后重新安装即可.

仅安装cuda计算套件

参照 Ubuntu 16.04 LTS + CUDA8.0 + cudnn6.0 中的步骤安装即可, 安装时仅选择 Cuda Library.

安装Pytorch

安装pytorch1.7

注意: 目前(2020.1.6)conda库里还没有 cuda11.1 对应的pytorch, 所以如果下面的命令输入 cudatoolkit=11.1 则会下载cpu版的pytorch, 故此这里输入 cudatoolkit=11.0.

conda create -n rtx3090  # 创建新的环境 rtx3090
conda install pytorch torchvision torchaudio cudatoolkit=11.0 -c pytorch

输入后会提示如下信息:

安装完成后, 进入python 解释环境, 输入如下命令查看是否安装成功:

import torch
torch.__version__
torch.cuda.is_available()
torch.cuda.get_device_name(0)
torch.cuda.get_device_name(1)

本人在Python原生环境下配置有 pytorch1.6+cuda10.1 环境, Anaconda下创建的 rtx3090 环境下配置有 pytorch1.7.1+cuda11.0, 使用上述命令查看配置后的环境,可得到如下结果:

源码安装pytorch1.8

参照官方步骤, 首先下载pytorch，torchvision源码：

git clone --recursive https://github.com/pytorch/pytorch
cd pytorch
git submodule sync
git submodule update --init --recursive

在conda中创建新环境 pytorch18：

conda create -n pytorch18 python=3.7.9 # 创建新的环境 pytorch18

安装公共依赖：

conda install numpy ninja pyyaml mkl mkl-include setuptools cmake cffi typing_extensions future six requests dataclasses
# Add LAPACK support for the GPU if needed
conda install -c pytorch magma-cuda111  # or the magma-cuda* that matches your CUDA version from https://anaconda.org/pytorch/repo

执行如下命令编译安装:

export CMAKE_PREFIX_PATH=${CONDA_PREFIX:-"$(dirname $(which conda))/../"}
python setup.py install

接下来是漫长的等待过程.

如果提示 Parse error. Expected a command name, got unquoted argument with text, 可能是你的pytorch中CMakeList.txt的编码方式不对,这有在你从Windows拷贝到Ubuntu时会发生, 修改为utf-8编码即可.

如果提示找不到CUDNN版本（Found cuDNN: v?）, 如下，请检查CUDNN的安装过程，应该出错了，参见官方步骤

-- Caffe2: CUDA detected: 11.1
-- Caffe2: CUDA nvcc is: /usr/local/cuda/bin/nvcc

源码安装torchvision

git clone --recursive https://github.com/pytorch/vision.git
cd vision
python setup.py install

测试结果如下, 由测试结果知, 3090与1080ti性能相当, 甚至还没有1080ti好, 这与官网宣称的性能差距甚远, 另外本人在自己写的比较复杂的网络模型上测试, 3090的性能更差.

由于安装的Pytorch为二进制版, 其对应cuda版本为11.0, 而本文安装cuda版本为11.1, 担心这个会影响3090性能的发挥, 因而重新安装cuda11.0, 测试结果如下, 可见cuda版本没有影响

Tensorflow 上测试结果

CFAR图像分类

所用Tensorflow版本为2.4.0, CUDA为11.0, CUDNN为8005, 数据集为CFAR10, 测试代码如下:

train_images, test_images = train_images / 255.0, test_images / 255.0

class_names = ['airplane', 'automobile', 'bird', 'cat', 'deer',
               'dog', 'frog', 'horse', 'ship', 'truck']

plt.figure(figsize=(10,10))

    plt.xticks([])
    plt.yticks([])
    plt.grid(False)
    plt.imshow(train_images[i], cmap=plt.cm.binary)
    # The CIFAR labels happen to be arrays, 
    # which is why you need the extra index
    plt.xlabel(class_names[train_labels[i][0]])
plt.show()

model = models.Sequential()
model.add(layers.Conv2D(32, (3, 3), activation='relu', input_shape=(32, 32, 3)))

model.add(layers.MaxPooling2D((2, 2)))

model.summary()

model.add(layers.Flatten())
model.add(layers.Dense(64, activation='relu'))
model.add(layers.Dense(10))

model.summary()

model.compile(optimizer='adam',
              loss=tf.keras.losses.SparseCategoricalCrossentropy(from_logits=True),
              metrics=['accuracy'])

tstart = time.time()
history = model.fit(train_images, train_labels, epochs=10, 
                    validation_data=(test_images, test_labels))
tend = time.time()
print("Training time: ", tend - tstart)

plt.plot(history.history['accuracy'], label='accuracy')
plt.plot(history.history['val_accuracy'], label = 'val_accuracy')
plt.xlabel('Epoch')
plt.ylabel('Accuracy')
plt.ylim([0.5, 1])
plt.legend(loc='lower right')

tstart = time.time()
test_loss, test_acc = model.evaluate(test_images,  test_labels, verbose=2)
tend = time.time()
print("Testing time: ", tend - tstart)

print(test_acc)

测试结果如下, 可见, 在Tensorflow下, 3090的性能也很一般, 跟1080ti差不多:

需要注意的事项

Tensor Float32

根据Pytorch文档所述 TF32 on Ampere, 30系列的GPU支持Tensor Float32类型的计算，如果打开则会使用相关加速单元计算，要比普通的浮点数计算快，但是精度会下降, 在Pytorch中默认是打开的。

# The flag below controls whether to allow TF32 on matmul. This flag defaults to True.
torch.backends.cuda.matmul.allow_tf32 = True

# The flag below controls whether to allow TF32 on cuDNN. This flag defaults to True.
torch.backends.cudnn.allow_tf32 = True

奇怪的现象

基础环境为:

系统: Ubuntu16.04
CUDA: 8.0, 9.0, 10.1, 11.1 共存

第一种Pytorch版本配置:

原生Python环境Pytorch配置 1.6.0+cu101
Anaconda环境Pytorch配置: 1.8.0.dev20210106+cu110

第二种Pytorch版本配置:

原生Python环境Pytorch配置 1.9.0.dev20210208+cu110 + Python3.6.11
Anaconda环境Pytorch配置: 1.8.0.dev20210208+cu110 + Python3.7.3

第三种Pytorch版本配置:

原生Python环境Pytorch配置 1.8.0.dev20210208+cu110 + Python3.6.11
Anaconda环境Pytorch配置: 1.8.0.dev20210208+cu110 + Python3.7.3

最后发现只要原生Python中的Pytorch版本与Anaconda中的Pytorch版本不一致, 一在GPU上运行程序就会卡死, 只有版本一致时才不卡.

Pytorch 不同版本在不同设备上的性能测试

使用 torch.manual_seed(seed) 设置随机数种子, 保证每次运行产生的网络初始权重相同
torch.backends.cudnn.benchmark 是否允许CUDNN自己寻找较快的卷积实现, 不同device, 不同的卷积, 都会带来卷积实现的速度和精度的差异, 若网络结构非动态, 且数据大小不变化, 可设置为 True, 反之, 应设为 False, 否则反而寻找快速实现会暂用大量时间.
torch.backends.cudnn.deterministic 是否禁止CUDNN使用不确定性算法, 若为 True 则使用确定性算法, 此设置即影响速度又影响精度.
torch.backends.cuda.matmul.allow_tf32 是否允许使用 TensorFloat32 (TF32) 张量核, 设置为 True 会提升速度, 但精度会有损失, 仅ampere 架构GPU支持, 对于不支持的GPU, 此设置不奏效, 不影响
torch.backends.cudnn.allow_tf32 是否允许CUDNN使用 TensorFloat32 (TF32) 张量核, 设置为 True 会提升速度, 但精度会有损失, 仅ampere 架构GPU支持, 对于不支持的GPU, 此设置不奏效, 不影响

pytorch, nvidia ampere tensor cores :speed vs precision, 精度损失挺大的.

为便于比较, 现将时间测试结果如下:


PyTorch 1.8.0.dev20210208+cu110 + RTX 3090+CUDA11

3090+CUDA11结果

测试配置如下:

CUDATF32=False, CUDNNTF32=False, Benchmark=False, Deterministic=False 运行2次
CUDATF32=False, CUDNNTF32=False, Benchmark=False, Deterministic=True 运行2次
CUDATF32=False, CUDNNTF32=False, Benchmark=True, Deterministic=False 运行2次
CUDATF32=False, CUDNNTF32=False, Benchmark=True, Deterministic=True 运行2次
CUDATF32=True, CUDNNTF32=True, Benchmark=False, Deterministic=False 运行2次

CUDATF32=True, CUDNNTF32=True, Benchmark=True, Deterministic=False 运行2次
CUDATF32=True, CUDNNTF32=True, Benchmark=True, Deterministic=True 运行2次

由结果可得如下结论:

无论 Benchmark, Deterministic 取何种设置, TF32基本无加速, 而由于精度损失导致指标有所下降.
Benchmark 加速比较大 (无论 CUDATF32, CUDNNTF32, Deterministic 取何值)
Deterministic 加速比很小 (无论 CUDATF32, CUDNNTF32, Benchmark 取何值)

时间结果如下:

CUDATF32=False, CUDNNTF32=False, Benchmark=False, Deterministic=False : train: 54s, valid: 14s
CUDATF32=False, CUDNNTF32=False, Benchmark=False, Deterministic=True : train: 55s, valid: 14s
