I have a python file which has many 'def' values in it. When I try to integrate the python file with android studio, I get a type error. The input is a image file and I want the lowerRange and upperRange to be based on that image, so I cannot define a value to them, since image size can vary everytime.
import numpy as np
import cv2
import os
import matplotlib.pyplot as plt
from PIL import Image
def host(croppedImage,lowerRange, upperRange):
mask_yellow = cv2.inRange(croppedImage,lowerRange,upperRange)
dilatation_type = cv2.MORPH_RECT
dilatation_size = 1
element = cv2.getStructuringElement(dilatation_type, (dilatation_size + 2, dilatation_size+2), (dilatation_size, dilatation_size))
dilated_mask_image = cv2.dilate(mask_yellow, element)
return dilated_mask_image
def DrawContourRect(contour):
rect = cv2.minAreaRect(contour)
return cv2.boxPoints(rect)
-----------------------------This is just a part of code---------------------------------
And this is the xml code for python object:
PyObject pyo = py.getModule("file");
PyObject obj = pyo.callAttr("host", imageString);
And the error is this:
com.chaquo.python.PyException: TypeError: detect() missing 2 required positional arguments: 'lowerRange' and 'upperRange'
at <python>.chaquopy_java.call(chaquopy_java.pyx:285)
at <python>.chaquopy_java.Java_com_chaquo_python_PyObject_callAttrThrows(chaquopy_java.pyx:257)
Is there any way to solve this problem and how can the chaquopy read each and every 'def' value (host and DrawContourRect.
The error message and code don't seem to match, but I assume that host and detect are either the same function, or that they have the same signature.
If that's correct, then the problem is simply that you're passing 1 argument to a function that requires 3. If you want the lowerRange and upperRange to be based on the image, then you'll have to either:
