pos enet - python вызывает проблему с атрибутом tensorflow

Question

Я пробую Pos enet - python от Ross Whigtman, доступный в этом GitHub:

https://github.com/rwightman/posenet-python

Я использую следующий код чтобы проверить это на одном изображении:

model = 101
scale_factor = 1.0
notxt = 'store_true'
image_dir = './images'
output_dir = './output'

def main():

with tf.compat.v1.Session() as sess:
    model_cfg, model_outputs = posenet.load_model(model, sess)
    output_stride = model_cfg['output_stride']

    if args.output_dir:
        if not os.path.exists(output_dir):
            os.makedirs(output_dir)

    filenames = [
        f.path for f in os.scandir(image_dir) if f.is_file() and f.path.endswith(('.png', '.jpg'))]

    start = time.time()
    for f in filenames:
        input_image, draw_image, output_scale = posenet.read_imgfile(
            f, scale_factor=scale_factor, output_stride=output_stride)

        heatmaps_result, offsets_result, displacement_fwd_result, displacement_bwd_result = sess.run(
            model_outputs,
            feed_dict={'image:0': input_image}
        )

        pose_scores, keypoint_scores, keypoint_coords = posenet.decode_multiple_poses(
            heatmaps_result.squeeze(axis=0),
            offsets_result.squeeze(axis=0),
            displacement_fwd_result.squeeze(axis=0),
            displacement_bwd_result.squeeze(axis=0),
            output_stride=output_stride,
            max_pose_detections=10,
            min_pose_score=0.25)

        keypoint_coords *= output_scale

        if args.output_dir:
            draw_image = posenet.draw_skel_and_kp(
                draw_image, pose_scores, keypoint_scores, keypoint_coords,
                min_pose_score=0.25, min_part_score=0.25)

            cv2.imwrite(os.path.join(output_dir, os.path.relpath(f, image_dir)), draw_image)

        if not notxt:
            print()
            print("Results for image: %s" % f)
            for pi in range(len(pose_scores)):
                if pose_scores[pi] == 0.:
                    break
                print('Pose #%d, score = %f' % (pi, pose_scores[pi]))
                for ki, (s, c) in enumerate(zip(keypoint_scores[pi, :], keypoint_coords[pi, :, :])):
                    print('Keypoint %s, score = %f, coord = %s' % (posenet.PART_NAMES[ki], s, c))

    print('Average FPS:', len(filenames) / (time.time() - start))


if __name__ == "__main__":
    main()

Однако это вызывает следующую ошибку:

---------------------------------------------------------------------------

    166         with tf.Session() as sess:
    167             sess.run(init)

AttributeError: module 'tensorflow' has no attribute 'global_variables_initializer'

Может ли кто-нибудь предоставить информацию о том, что вызывает эту ошибку и как ее исправить ? Спасибо.
