一、训练一个新的画风迁移网络

nohup python style.py –checkpoint-dir ./checkpoint/rain-princess –style ./rain-princess.jpg –test ./military_museum.jpg –test-dir ./test_images/rain-princess > style_py_stdout.log 2>&1 &

nohup python style.py –checkpoint-dir ./checkpoint/rain-princess –style ./rain-princess.jpg –test ./military_museum.jpg –test-dir ./test_images/rain-princess > style_py_stdout.log 2>&1 &

1.1 训练过程中GPU使用情况

nvidia-smi

1.2训练结束（GPU：GTX 1080 Ti，耗时7.5h）

二、评估训练好的画风迁移网络

nohup python evaluate.py –checkpoint ./checkpoint/rain-princess/ –in-path ./in-path/central_tv_tower.jpg –out-path ./out-path/ > evaluate_py.log 2>&1 &

nohup python evaluate.py –checkpoint ./checkpoint/rain-princess/ –in-path ./in-path/central_tv_tower.jpg –out-path ./out-path/ >> evaluate_py.log 2>&1 &

左侧为原图，右侧为渲染后的图，画风为 rain-princess

三、渲染视频

nohup python transform_video.py –checkpoint ./checkpoint/rain-princess/ –in-path ./in-path/Little_Kitten_Playing_His_Toy_Mouse.mp4 –out-path ./out-path/Little_Kitten_Playing_His_Toy_Mouse_render.mp4 –tmp-dir ./tmp-path/ > ./transform_video_py.log 2>&1 &

GPU使用情况

渲染结果

四、错误处理

1.ffmpeg 需通过conda安装，直接命令行安装不行，安装命令： conda install -c conda-forge ffmpeg

2.缺libx264编码库

安装之：

git clone git://git.videolan.org/x264.git

cd x264

./configure –enable-shared –enable-static –disable-asm

make && make install
