is it possible to use your trained model just for detection purpose ?

Of course, you can use it. The detection part is the base for good tracking performance. In this case, they aim to use almost every detection box to improve the tracking step. With this in mind, you can use the model just for detection without sending the boxes to the tracker.

Thank you for your response.

I have used your trained model on mix dataset as a detector with the deepsort tracker. Though it is not related to ByteTracker . would you find any reason for the below traceback.

please help me to fix it

for imagePath in imagePaths:

load the image, pre-process it, and store it in the data list

print(imagePath)  #here I have printed the imagename
image = cv2.imread(imagePath)
image = cv2.resize(image, (28, 28))   # 28, 28
image = img_to_array(image)
data.append(image)

if(type(image) == type(None)): passelse: image = cv2.resize(image, (h, w), interpolation=cv2.INTER_AREA)

import cv2

image = cv2.imread('noexist.jpg')try: resize = cv2.resize(image, (64,64))except cv2.error as e: print('Invalid frame!') cv2.waitKey()

I had the same problem，I have used his trained model on mix dataset as a detector with the deepsort tracker too. I wonder if you have solved your problem
