Hello. I am working on this tutorial: https://pytorch.org/tutorials/intermediate/torchvision_tutorial.html# 4. I trained model and made predictions with py file below:
from PIL import Image
import torch
import numpy as np
from torchvision import transforms
from torch.autograd import Variable
import cv2


loader = transforms.Compose([transforms.ToTensor()])

def img_loader(img_path):
    img = Image.open(img_path)
    img = img.convert('RGB')
    img = loader(img).float()
    img = Variable(img, requires_grad=True)
    return img.cuda()
    
path = r't4.png'

model = torch.load('network')

model.eval()
img_arr = img_loader(path)
with torch.no_grad():
    pred = model([img_arr])

iter_num = len(pred[0]['boxes'])

img1 = cv2.imread(path)

#where I draw bboxes
for i in range(iter_num):
    tl =  (pred[0]['boxes'][i][0],pred[0]['boxes'][i][1])
    br = (pred[0]['boxes'][i][2],pred[0]['boxes'][i][3])
    img1 = cv2.rectangle(img1,tl,br, (0,0,255), 2)

output = Image.fromarray(pred[0]['masks'][0, 0].mul(255).byte().cpu().numpy())
print(output)
cv2_output = np.array(output)
cv2_output = cv2_output[:, :-1].copy()



cv2.imshow('out', img1)
cv2.imwrite('todiscuss.png', img1)
cv2.waitKey(0)
print('Done')


When I draw boundary boxes I got this result: todiscuss716×486 283 KB
As it seen in image, pred = model(img) returns lots of bboxes. Is there any way to set a threshold for returned bboxes?
