Pytorch-openposeを利用

当初、次のリポジトリの資源をgit cloneしようとしたが、__tesorflow=1.4.1が入れられなかった__ため、利用を諦めた。

変わりに、PyTorch実装の資源を次から入れることにした。

以下から、body_pose_model.pth hand_pose_model.pthをダウンロード

両ファイルを、./model直下に移動

Terminal

以下のエラーメッセージが出た。

RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

Googleで調べると、numpyのバージョンに問題があるらしい。
requirement.txtに列挙されているnumpuのバージョン番号を見てみる。

Terminal

バージョンは特に指定されていない。

以下のサイトから、test.pyを写経。

test.py
import os
import cv2
import copy
from src import util
from src.body import Body
 
INPUT_FILE_NAME = "test.jpg"
 
if __name__ == "__main__":
 
    body_estimation = Body('model/body_pose_model.pth')
 
    target_image_path = 'images/' + INPUT_FILE_NAME
    oriImg = cv2.imread(target_image_path)  # B,G,R order
    candidate, subset = body_estimation(oriImg)
    canvas = copy.deepcopy(oriImg)
    canvas = util.draw_bodypose(canvas, candidate, subset)
 
    basename_name = os.path.splitext(os.path.basename(target_image_path))[0]
 
    result_image_path = "result/pose_" + basename_name + ".jpg"
    cv2.imwrite(result_image_path, canvas)

imageファイルをimages直下に格納。
ファイル名は、pose_test.jpg

以下の次のアドバイスを採用

pip install numpy --upgrade works, something has to be updated in the files, when you figure out what, could you tell me please, thanks

Terminal
electron@diynoMacBook-Pro pytorch-openpose % pip3 install numpy --upgrade

（・・・省略・・・）

tensorflow 2.5.0 requires numpy~=1.19.2, but you have numpy 1.21.1 which is incompatible.
Successfully installed numpy-1.21.1

以下のサイトの次のアドバイスを採用

AssertionError: Torch not compiled with CUDA enabled
はい、cudaね。test_video.pyの110行目と134行目に.cuda()があるので、.cuda()だけを削除し、再び実行。

以下をコメントアウト

print(f"Torch device: {torch.cuda.get_device_name()}")

Terminal
electron@diynoMacBook-Pro pytorch-openpose % cp demo_camera.py demo_camera_cpu.py

今度はちゃんと動いた:sunny:

Webカメラの画像が動画で表示され、自分の顔に骨格線が重畳された画像が表示された。

体を動かすと、ややタイムラグを伴って、骨格線も追従してついてきた。

test.pyを書き換えて、もう２つ、画像ファイルを加工してみる

取り扱う画像ファイルのパスを、コマンドライン引数で受け取るように書き換える。

# 動画ファイル名をコマンドライン引数から受け取る

    target_image_path = file
    oriImg = cv2.imread(target_image_path)  # B,G,R order
    candidate, subset = body_estimation(oriImg)
    canvas = copy.deepcopy(oriImg)
    canvas = util.draw_bodypose(canvas, candidate, subset)
 
    basename_name = os.path.splitext(os.path.basename(target_image_path))[0]
