# Steps of setting mediapipe model path

## Step 1. Get the MediaPipe package path

Create a python cmd

import mediapipe as mp
import os
MP_PATH = os.path.dirname(mp.__file__)
MP_PATH.replace('\\', '/')

## Step 2. Go to MediaPipe package folder
進入```MP_PATH/python/solutions/```，這個資料夾裡面控制了MP所有ML model的路徑
以修改mediapipe的holistic model為例，總共有三個檔案路徑
holistic.py，line 52~63,

_BINARYPB_FILE_PATH = 'mediapipe/modules/holistic_landmark/holistic_landmark_cpu.binarypb'


def _download_oss_pose_landmark_model(model_complexity):
  """Downloads the pose landmark lite/heavy model from the MediaPipe Github repo if it doesn't exist in the package."""

  if model_complexity == 0:
    download_utils.download_oss_model(
        'mediapipe/modules/pose_landmark/pose_landmark_lite.tflite')
  elif model_complexity == 2:
    download_utils.download_oss_model(
        'mediapipe/modules/pose_landmark/pose_landmark_heavy.tflite')

修改以上路徑到你設定的路徑, E.g.,

_BINARYPB_FILE_PATH = 'path-to-the-model-structure'


def _download_oss_pose_landmark_model(model_complexity):
  """Downloads the pose landmark lite/heavy model from the MediaPipe Github repo if it doesn't exist in the package."""

  if model_complexity == 0:
    download_utils.download_oss_model(
        'path-to-the-model-weights-1')
  elif model_complexity == 2:
    download_utils.download_oss_model(
        'path-to-the-model-weights-2')

## Step 3. Relocate MP model
進入```MP_PATH/modules```，如果model有被下載過，裡面會有.pb或.tflite的檔案。
建議複製整個資料夾到你指定的路徑, E.g., ```holistic_landmark```
