ubuntu20 caffe opencv4 conda python3.7.10

如果你只想要pycaffe,那可以conda+python3.7.10,然后conda install caffe-gpu

环境

ubuntu20
cuda11.7 cudnn8(不过caffe似乎不能加速cudnn8
conda python3.7.10
假设你已经装了opencv4,cuda11.7,cudnn8
opencv4安装教程
cuda和cudnn安装教程
建议ubuntu和anaconda,pip都换个源(ubuntu换源,anaconda换源,建议ustc/bfsu)

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler -y
sudo apt-get install --no-install-recommends libboost-all-dev -y
sudo apt-get install libopenblas-dev liblapack-dev libatlas-base-dev -y
sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev -y
sudo apt-get install git cmake build-essential -y

python

conda create -n caffe_env python==3.7.10 pip setuptools
conda activate caffe_env
pip install numpy scipy scikit-image matplotlib ipython h5py leveldb networkx nose pandas python-dateutil protobuf python-gflags pyyaml pillow six google-api-python-client

conda install pydot graphviz boost

这里用conda装boost是因为apt似乎只会装和系统python一样的版本的boost

 修改为:
cv::IMREAD_GRAYSCALE

修改src/caffe/layers/window_data_layer.cpp

#endif
 
  以下为原代码(用于定位):
// See PR #1236

编译

先切一下环境(也许不需要)

conda activate caffe_env
make all -j8

测试

先切一下环境(也许不需要)

conda activate caffe_env

这里是因为boost_python是conda装的,默认不在系统里,所以先改一下LD_LIBRARY_PATH

export LD_LIBRARY_PATH="/home/icml/miniconda3/envs/caffe_env/lib:$LD_LIBRARY_PATH"
make runtest -j8

在这里插入图片描述

编译pycaffe

先切一下环境(也许不需要)

conda activate caffe_env

需要的python包在最前面创建python的时候就已经安装了

make pycaffe -j8

测试

先切一下环境

conda activate caffe_env

需要的python包在最前面创建python的时候就已经安装了

这里是因为boost_python是conda装的,默认不在系统里,所以先改一下LD_LIBRARY_PATH

export LD_LIBRARY_PATH="/home/icml/miniconda3/envs/caffe_env/lib:$LD_LIBRARY_PATH"

然后

export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION='python' 

这一句是为了防止出现下面这个错误
ubuntu20 caffe opencv4 conda python3.7.10_第1张图片
开始测试

make pytest -j8

ubuntu20 caffe opencv4 conda python3.7.10_第2张图片

修改环境变量

在~/.bashrc的后面加入

export LD_LIBRARY_PATH="/home/icml/miniconda3/envs/caffe_env/lib:$LD_LIBRARY_PA>
export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION='python' 
export PYTHONPATH="${PYTHONPATH}:/mnt/data/caffe-master/python"

然后

source ~/.bashrc

如果你有zsh,就再做一遍类似的操作

测试

C++

mnist

首先cd进入caffe的目录

sh data/mnist/get_mnist.sh
sh examples/mnist/create_mnist.sh
nano examples/mnist/lenet_solver.prototxt

修改最后的max_iter和solver_mode(虽然我没改

开始训练

time sh examples/mnist/train_lenet.sh

花了1min,还行把
