yolox_nano.pth转换yolox_nano.onnx文件报错：Missing key(s) & Unexpected key(s) in state_dict...（自己的数据集训练的模型）

最近我自己的电脑上面尝试训练yolox_s和yolox_nano模型，使用的都是我自己的数据集，只有1类，以下博客就是我自己环境配置、训练还有遇到的问题的过程，这些我都写在了一个博客上面：
https://blog.csdn.net/ELSA001/article/details/120918082?spm=1001.2014.3001.5501
这些问题我都一一解决了，但是我想要把训练好的yolox_nano.pth模型转换成yolox_nano.onnx文件，然后转换成ncnn相关的文件来部署到安卓机上面。
在转换之前我把.\exps\default文件夹下的nano.py改成了前面的版本：

如果不改变的话，把官网上的coco数据集的yolox_nano.pth模型转换成yolox_nano.onnx文件的就会报错，我也不知道为啥。
不过我在使用自己的数据集的yolox_nano.pth模型转换成yolox_nano.onnx文件的时候遇到了问题。
报错信息如下：

RuntimeError('Error(s) in loading state_dict for {}:\n\t{}'.format(
RuntimeError: Error(s) in loading state_dict for YOLOX:
Missing key(s) in state_dict: "backbone.backbone.dark2.0.dconv.conv.weight", "backbone.backbone.dark2.0.dconv.bn.weight".....
Unexpected key(s) in state_dict: "backbone.backbone.dark2.0.conv.weight", "backbone.backbone.dark2.0.bn.weight"......

完整报错信息如下：

这些报错信息都是我在没有改变export_onnx.py时候的报错，我之前还把官网上面的80类的coco数据集的yolox_nano.pth模型转换成yolox_nano.onnx文件，但是可以成功转换：


而我已经修改了yolox_base.py里面的num_classes、depth、width还有input_size这些：

但是还是不能转换！
我看了网上很多教程，发现可以使用replace操作把权重文件的backbone.去掉，然后我操作了一下export_onnx.py这个文件：
把它改成这样：

但是依然有报错，只是稍微不一样了而已：


我发现这新的错误里面的有些变了，有些却没有变。
完整报错信息如下：

我训练好的的yolox_nano.pth是没问题的，可以正常预测（推理）：


我认为是我使用自己的1类的数据集加上单卡训练加上没有使用半精度训练的原因，不过我之前还试过直接把model. load_state_dict(ckpt)这个代码直接注释掉：

这个model. load_state_dict(ckpt)的代码应该是加载训练好的模型的，但是我没有使用这个然后进行转换，发现可以转换成功：



onnx文件打开看发现也没问题：
最后我也成功转换了ncnn文件：

但最后部署到安卓上面的时候就出问题了，完全检测不到：

我认为这明显就是.pth文件转换.onnx文件的时候出了问题，因为我完全就是没有加载ckpt模型。
我在这里卡了好长时间，希望有过使用自己的数据集训练过yolox_nano.pth模型来部署到安卓上面的大佬可以教我一下，十分感谢，这个部署对我来说很重要。
