Hi @Pawan_Jha Could you make sure that your argument is initialized? Also, @vedantnarayan, if by any chance you still have the issue, see here: [изображение] Python 64 bit compatibility with UiPath Studio 2018.4.0 Help hey @pratosha.hegde Just use this path and better to set Auto in version selection. C:\Users\hegdepra\AppData\Local\Programs\Python\Python35\ one thing - The Above path is not look good. Python installed on your system? if it is show it should be like C:\Python36_64 or if you will have installed with Visual Studio then path will be like "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64" but if your python.exe is there exists that use that path how i mentioned above. Let…

Main (13).xaml (4.9 KB) Kindly find my attachment. (I’m Ajisha_P)

i attached the file. Can you please check it

Can you attach imgprcs.py file also

import cv2 import numpy as np import matplotlib.pyplot as plt from scipy.stats import itemfreq #flags = [i for i in dir(cv2) if i.startswith(‘COLOR_r’)] #print(flags) def itemfreq(a): items, inv = np.unique(a, return_inverse=True) freq = np.bincount(inv) return np.array([items, freq]).T #def rgb_2_hex(rgb): return ‘#%02x%02x%02x’ % rgb img = cv2.imread(‘img2.png’) average_color = [img[:, :, i].mean() for i in range(img.shape[-1])] arr = np.float32(img) pixels = arr.reshape((-1, 3)) n_colors = 5 criteria = (cv2.TERM_CRITERIA_EPS + cv2.TERM_CRITERIA_MAX_ITER, 200, .1) flags = cv2.KMEANS_RANDOM_CENTERS _, labels, centroids = cv2.kmeans(pixels, n_colors, None, criteria, 10, flags) palette = np.uint8(centroids) quantized = palette[labels.flatten()] quantized = quantized.reshape(img.shape) dominant_color = palette[np.argmax(itemfreq(labels)[:, -1])] #print(b’#'+b16encode(bytes(dominant_color))) #rgb2hex(dominant_color) print("Average Color : ", average_color) print(“Dominant Color :”, dominant_color) #rgb_2_hex((dominant_color)) #print(rgb_2_hex(hex())) hex = (dominant_color[0] << 16) + (dominant_color[1] << 8) + (dominant_color[2]) print(hex)

image you can give anything i cant upload the file. because i m new user. This is the code

Please follow the bellow steps. Use Python Scope Activity and select the version of the Python and mention the installation path of the Python. Use Load Python Script activity and mention the path of the script(.py).then create a variable with the data type called PythonObject and assign that variable to Result property of this activity. Use Invoke Python Method activity and mention the Method in the property called Name, what you have defined in your Python code.Then you have to pass the Python Object in the property called “Instance”(as output created in the step 2.).Create a variable which of type PythonObject and assign that variable to property called “Output”. Use Get Python Object activity,then you have to pass the Python Object in the property called “Python Object”(as output created in the step 3.) 5.Create a variable to store the value which is return from your Python and assign that variable to the property called “Output”.Then print the result using write line.

Thank you for your detailed explanation… I have already done everything as you described (and also looked at your code that you posted above) → still getting the same exception : “Error initializing python engine”. I think I need to install 32bit Python (as I have already seen that many are saying it doesn’t work with the 64bit)… The other thing I wanted to ask is: In case I have more functions in my python script - > then your way won’t work? Correct me if I am wrong… Since here I was able to use just one method but in my script I have around 6 - > that means it is better to use Run Python Script Activity within Python Scope? Thank you very much!!!

Hi, I am also trying to get a python script running… And I put the following into my code, but also getting an exception… (Before this, I tried the Path: “C:\Python27\python.exe” and I still have gotten the exception)…

Thanks!
