在Ubuntu上使用C++进行机器学习,可以按照以下步骤进行:
wget https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-Linux-x86_64.sh
chmod +x Miniforge3-Linux-x86_64.sh
./Miniforge3-Linux-x86_64.sh
conda init bash
source ~/.bashrc
conda update conda
conda create --name ml_env python=3.8
conda activate ml_env
TensorFlow:
使用C++ API编译安装TensorFlow:
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
git checkout refs/tags/v2.4.0
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package
./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
pip install /tmp/tensorflow_pkg/tensorflow-*.whl
Dlib:
安装Dlib:
conda install -c conda-forge dlib
OpenCV:
安装OpenCV:
conda install -c conda-forge opencv
ml_example.cpp
,并编写机器学习代码。以下是一个简单的TensorFlow C++示例:#include <tensorflow/cc/saved_model/loader.h>
#include <tensorflow/cc/saved_model/tag_constants.h>
#include <tensorflow/core/framework/tensor.h>
#include <tensorflow/core/public/session.h>
int main(int argc, char* argv[]) {
tensorflow::Scope root = tensorflow::Scope::NewRootScope();
// 加载模型
std::unique_ptr<tensorflow::Session> session(tensorflow::NewSession(tensorflow::SessionOptions(), root));
tensorflow::Status load_status = tensorflow::LoadSavedModel(tensorflow::SessionOptions(), {tensorflow::kSavedModelTagServe}, "/path/to/saved_model", {tensorflow::kSavedModelTagServe}, session.get());
if (!load_status.ok()) {
std::cerr << "Error loading model: " << load_status.ToString() << std::endl;
return 1;
}
// 运行模型
std::vector<tensorflow::Tensor> outputs;
tensorflow::Status run_status = session->Run({{"input", tensorflow::Tensor(tensorflow::DT_FLOAT, tensorflow::TensorShape({1, 28, 28, 1})})}, {"output"}, {}, &outputs);
if (!run_status.ok()) {
std::cerr << "Error running model: " << run_status.ToString() << std::endl;
return 1;
}
// 处理输出
for (const auto& output : outputs) {
std::cout << output.DebugString() << std::endl;
}
return 0;
}
g++ -std=c++11 ml_example.cpp -o ml_example -ltensorflow -I/path/to/tensorflow/include -L/path/to/tensorflow/lib -pthread
./ml_example
请注意,上述步骤中的路径(如/path/to/saved_model
和/path/to/tensorflow
)需要替换为实际的路径。此外,根据你的具体需求,可能还需要安装其他机器学习库和依赖项。
