Any good results from SegNet?

[farnaznouraei]

I wanted to ask if anyone has tested SegNet implementation on Pascal VOC 2012 and has gotten good results? I even trained it for only 20 images and still get very bad results (almost worse than random guessing) on the same training images! The loss never goes lower than 200000 and oscillates a lot.

@alexanderuo The Pascal data loader in this repo has a lot of issues. Most important one being that the resize function generates unwanted values in the label masks. I made some changes and made it work:

` import os from os.path import join as pjoin import collections import json import torch import numpy as np import scipy.io as io import matplotlib.pyplot as plt import glob import cv2

from PIL import Image from tqdm import tqdm from torch.utils import data as dt from torchvision import transforms import warnings

class pascalVOCLoader(dt.Dataset): """Data loader for the Pascal VOC semantic segmentation dataset.

Annotations from both the original VOC data (which consist of RGB images
in which colours map to specific classes) and the SBD (Berkely) dataset
(where annotations are stored as .mat files) are converted into a common
`label_mask` format.  Under this format, each mask is an (M,N) array of
integer values from 0 to 21, where 0 represents the background class.

The label masks are stored in a new folder, called `pre_encoded`, which
is added as a subdirectory of the `SegmentationClass` folder in the
original Pascal VOC data layout.

A total of four data splits are provided for working with the VOC data:
    train: The original VOC 2012 training data - 1464 images
    val: The original VOC 2012 validation data - 1449 images
    train_aug: The unique images present in both the train split and
               training images from SBD: - 8829 images (the unique members
               of the result of combining lists of length 1464 and 8498)

@farnaznouraei after I used your code, I got the following errors: can you fix it? Traceback (most recent call last): File "/datashare3/charis/code/recaps/pytorch-semseg-master1/train.py", line 229, in train(cfg, writer, logger) File "/datashare3/charis/code/recaps/pytorch-semseg-master1/train.py", line 44, in train t_loader = data_loader( File "/datashare3/charis/anaconda/envs/recap/lib/python3.8/typing.py", line 875, in new obj = super().new(cls, *args, **kwds) TypeError: object.new() takes exactly one argument (the type to instantiate)
