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-smi1.2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
