我正在尝试将一个文件从java传递到python。加载文件我用毕加索，因为我要得到宽度和高度。但是当我调用同一个文件将其传递给python时，它会给我一个错误。这是java代码：

Picasso.get().load(R.drawable.f21).into(new Target() {
                    @Override
                    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {

                        imageString = getStringImage(bitmap);
                        iv.setImageBitmap(bitmap);

                        PyObject pyo = py.getModule("Heat");
                        PyObject obj = pyo.callAttr("Python", bitmap, lrange, urange);
                        String str = obj.toString();
                        byte data[] = android.util.Base64.decode(str, Base64.DEFAULT);

                        Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
                        iv2.setImageBitmap(bmp);

我得到的错误是：

com.chaquo.python.PyException: TypeError: Expected Ptr<cv::UMat> for argument '%s'
            at <python>Heat.Python(Heat.py:9)  
            at com.chaquo.python.PyObject.callAttr(PyObject.java:209)

但是当我尝试从drawable加载图像时，它并没有成功地传递到python脚本中。它不会显示任何错误，但会显示以下消息：

I/Choreographer: Skipped 129 frames!  The application may be doing too much work on its main thread.

如何将图像从java传递到python脚本。
我的python代码是：

import numpy as np
import cv2
import os
import matplotlib.pyplot as plt
from PIL import Image

def Python(croppedImage,lowerRange, upperRange):
    mask_yellow = cv2.inRange(croppedImage,lowerRange,upperRange)
    dilatation_type = cv2.MORPH_RECT

hMin = 1
sMin = 0
vMin = 0

hMax = 107
sMax = 38
vMax = 265

output = image
wait_time = 30
lower = np.array([hMin, sMin, vMin])
upper = np.array([hMax, sMax, vMax])
print(lower,upper)

 hsv = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)
 mask = cv2.inRange(hsv, lower, upper)
