有关依赖DensePose安装的建议（recommendations about reliable DensePose installation）

[jjandnn]

pip install git+https://github.com/facebookresearch/detectron2.git@v0.6#subdirectory=projects/DensePose

选择v0.6，而不是main，main在linux下没问题。但是windows下无法编译。

其次，提醒大家，cv2的typing目录下的__init__.py文件要修改严谨。
如：D:\anaconda3\Lib\site-packages\cv2\typing_init_.py
第68-83行所有的赋值都缺了单引号‘‘，不严谨，会报错，应该改成：
if numpy.lib.NumpyVersion(numpy.version) > "1.20.0" and sys.version_info >= (3, 9):
NumPyArrayGeneric = 'numpy.ndarray[typing.Any, numpy.dtype[numpy.generic]]'
else:
NumPyArrayGeneric = 'numpy.ndarray'
if numpy.lib.NumpyVersion(numpy.version) > "1.20.0" and sys.version_info >= (3, 9):
NumPyArrayFloat32 = 'numpy.ndarray[typing.Any, numpy.dtype[numpy.float32]]'
else:
NumPyArrayFloat32 = 'numpy.ndarray'
if numpy.lib.NumpyVersion(numpy.version) > "1.20.0" and sys.version_info >= (3, 9):
NumPyArrayFloat64 = 'numpy.ndarray[typing.Any, numpy.dtype[numpy.float64]]'
else:
NumPyArrayFloat64 = 'numpy.ndarray'

这样detectron2在windows上就没相关问题了。

根據大佬提供的指令：
pip install git+https://github.com/facebookresearch/detectron2.git@v0.6#subdirectory=projects/DensePose
出現以下報錯，是因為沒有修改__init__.py文件的關係嗎？
求指導 QQ

detectron2.这个包编译安装，要求：windows c++库你得装着。
然后依赖: black, cloudpickle, future, fvcore, hydra-core, iopath, matplotlib, omegaconf, Pillow, pycocotools, pydot, tabulate, tensorboard, termcolor, tqdm, yacs
上面的依赖中pycocotools千万别漏了。
接着DensePose的安装依赖detectron2（Required-by: detectron2-densepose），所以：
1，pip install git+https://github.com/facebookresearch/detectron2.git@v0.6
2，pip install git+https://github.com/facebookresearch/detectron2.git@v0.6#subdirectory=projects/DensePose

需要装哪些c++运行库？

Hi @jjandnn, does this solved the issue? I am looking to determine if this is the correct solution and have an answer in English.

Thanks in advance.

Maybe a bit late but tried the fix today.

Working on Windows right now

• delete git+https://github.com/facebookresearch/detectron2@main#subdirectory=projects/DensePose from requirements.txt
• pip install -r requirements.txt
• pip install black, cloudpickle, future, fvcore, hydra-core, iopath, matplotlib, omegaconf, Pillow, pycocotools, pydot, tabulate, tensorboard, termcolor, tqdm, yacs
• pip install git+https://github.com/facebookresearch/detectron2.git@v0.6
• pip install git+https://github.com/facebookresearch/detectron2.git@v0.6#subdirectory=projects/DensePose
• git clone https://github.com/facebookresearch/detectron2.git

if you get an error launching python app.py on site-packages\detectron2\data\transforms\transform.py line 46 change from LINEAR to BILINEAR and now works
