OpenCV cv2.dnn.readNetFromCaffe gives Failed to parse NetParameter error

Im trying to follow a project using a pretrained caffe model to detect faces but get an error.

CODE

import numpy as np
import os.path

modelFile = “C:/Users/danie/PycharmProjects/FaceTrack/models/res10_300x300_ssd_iter_140000.caffemodel”
configFile = “C:/Users/danie/PycharmProjects/FaceTrack/models/deploy.prototxt”

assert os.path.exists(modelFile)
assert os.path.exists(configFile)

print(os.path.isfile(modelFile))
print(os.path.isfile(configFile))

net = cv2.dnn.readNetFromCaffe(configFile, modelFile)

ERROR

I would massivly appreciate any help. i have looked at loads of threads and cant see what im doing wrong

most likely you downloaded some html file instead of the “raw” prototxt
look at it with some txt editor, or

type models/deploy.prototxt

on the console

Thanks mate. That was super super helpful.

I was using “Save link as” to get ptototxt, tried instead just coping into a text file and that solved my problem.
