Variations-of-SFANet-for-Crowd-Counting代码复现

前文对Variations-of-SFANet-for-Crowd-Counting做了一点基础梳理，并对开源框架的可视化代码进行了验证，链接如下：

这里对训练和测试代码进行相关复现。

train.py代码测试

(1)预训练权重

由于训练代码有预训练权重，来自：GitHub - ZhihengCV/Bayesian-Crowd-Counting: Official Implement of ICCV 2019 oral paper Bayesian Loss for Crowd Count Estimation with Point Supervision

根据文献Bayesian Loss for Crowd Count Estimation with Point Supervision：https://arxiv.org/abs/1908.03684所述

预训练是在ImageNet 上进行的

（2）训练模型

由于本文改进了SegNet和SFA两个模型，因此在训练的时候要选择不同的模型

在regression_trainer.py中，注意选择不同的模型

<1>M_SFANet_UCF_QNRF

注意模型选择和路径的选择

UCF_QNRF数据集经过贝叶斯处理的流程同前文记录

预训练权重在前文链接中可以下载

处理好了就可以开始训练

训练报错记录

RuntimeError: Error(s) in loading state_dict for Model:

详细报错如下

网上查的都不好使，这里注意预训练权重的文件里不要放多个权重文件，只放UCF_QNRF对应的预训练权重就好
