to get this to run on windows #2

[21pl]

update based on adding PHALP

the following are my hacky steps to get the latest update to run on windows

install per conda instructions

there will be errors saying detectron2 cannot be built

comment out the following:
if 'PYOPENGL_PLATFORM' not in os.environ:
os.environ['PYOPENGL_PLATFORM'] = 'egl'
in:
hmr2/utils/mesh_renderer.py
hmr2/utils/renderer.py

change init_.py in configs to
CACHE_DIR = os.path.join(os.environ.get("USERPROFILE"), ".cache")

pip install cyphon

in vendor/detectron root folder install with
pip install -e .

then
pip install webdataset

run 'python demo.py' which will download a model file
untar this model file by hand from /Users/username/.cache

the following should now work for images
python demo.py

to get track.py to work
run the following from the root of 4d-human
git clone https://github.com/brjathu/PHALP.git

comment out the following in setup.py

"detectron2 @ git+https://github.com/facebookresearch/detectron2.git",

install phalp (at root of the new phalp directory)
pip install -e .[all]

in py_renderer
comment out
#os.environ['PYOPENGL_PLATFORM'] = 'egl'

phalp/configs/base.py change to
CACHE_DIR = os.path.join(os.environ.get("USERPROFILE"), ".cache") # None if the variable does not exist

and then add the following to phalp.py

import requests
import shutil

(additions/commenting from line606...)

    if not os.path.exists(smpl_path):
        # We are downloading the SMPL model here for convenience. Please accept the license
        # agreement on the SMPL website: https://smpl.is.tue.mpg.
        os.makedirs(os.path.join(CACHE_DIR, "phalp/3D/models/smpl"), exist_ok=True)
        #os.system('wget https://github.com/classner/up/raw/master/models/3D/basicModel_neutral_lbs_10_207_0_v1.0.0.pkl')
        with requests.get('https://github.com/classner/up/raw/master/models/3D/basicModel_neutral_lbs_10_207_0_v1.0.0.pkl', stream=True) as r:
            with open('basicModel_neutral_lbs_10_207_0_v1.0.0.pkl', 'wb') as f:
                shutil.copyfileobj(r.raw, f)
        convert_pkl('basicModel_neutral_lbs_10_207_0_v1.0.0.pkl')
        #os.system('rm basicModel_neutral_lbs_10_207_0_v1.0.0.pkl')
        os.remove('basicModel_neutral_lbs_10_207_0_v1.0.0.pkl')
        #os.system('mv basicModel_neutral_lbs_10_207_0_v1.0.0_p3.pkl ' + smpl_path)
        shutil.move('basicModel_neutral_lbs_10_207_0_v1.0.0_p3.pkl ' , smpl_path)

the following should now work
python track.py video.source="example_data/videos/gymnasts.mp4"

I have had success with detectron2 this way. : https://stackoverflow.com/a/72784255/22334744

And I needed to put SMPL_NEUTRAL.pkl into .cache\phalp\3D\models\smpl. https://github.com/sampepose/smpl_models/tree/master

[carlosedubarreto]

The main problem is in this part

for windows it usually doenst work because the code is based onllinux commands, and not on python ones.

The easiest way it to make what @toyxyz says.

Also add the same "SMPL_NEUTRAL.pkl" to your "%HOMEPATH%.cache\4DHumans\data\smpl" folder

Thanks folks! I don't have a windows machine to test but if someone wants to open a PR with these changes, I'd be happy to review and merge :)

By any chance did you bump into this error ? ( before installing PHALP )

@hbardak I saw that problem, try to get an older version of detectron, maybe it will work.
from what I've read, the compiler option is available only on torch2.0 upwards

[hbardak]

It took me sweat and blood to compile detectron2 :-) Following your instruction on #36

Any ideas which version I should build ?
