如果是通过文件的话，你可以自己仿照my_dataset.py里面的get_xxxx_data_loader，去做一个自己的dataloader，就类似于predict的时候差不多。
如果是PIL读入的图片的话，可以参考pytorch的api，用transform把图片变灰度图，变尺寸，转成tensor。然后对tensor进行reshape把图片的三维tensor变成模型需要的四维的。
然后仿照captcha_predict.py的代码，把图片的tensor变成Variable，然后调用cnn的模型进行前向传播，然后再把onehot形式的label按4个位置分别取最大值，最后输出4个字符的结果。

实在不会用，用captcha_predict.py可以，但是我想在其它地方单独传入一张图片名称得到返回结果如何做呢？
实际使用时，并不是从本地文件夹打开，而很有可能直接传一张图片。所以你需要按照 seastarmanager 的建议，将图片进行特征数字化、归一化和灰度处理。要注意的是，图片尺寸大小的兼容问题。假如你训练的时候用的是 160*60，那么在预测时也要用这个大小。
