4_move_find_into_model

简介:
在controller中经常要对某一个model做同一种查询,这样会造成代码重复,为了符合DRY原则,将查询放到model里。
接着第三节的例子:
在task Model里定义类方法:
 
那么在task_controller和projects_controller里就可以调用这个方法:

Warning: Can save best model only with val_acc available, skipping
本文解决了在使用DenseNet网络结构保存最优模型时出现的"Warning: Can save best model only with val_acc available, skipping"问题,方法是将`ModelCheckpoint`回调函数中的`monitor`参数值从`val_acc`改为`val_accuracy`。

解决AttributeError: ‘model‘ object has no attribute ‘copy‘
原因是没有使用model.state_dict()进行模型保存,但是使用了model.load_state_dict()加载模型。这两者要配套使用。

解决spacy3.2报错:Can‘t find model ‘en‘.
(1)下载spacy一直没成功,把pip install spacy改成conda install spacy就可以了; (2)在命令行输入 python3 -m spacy download en 来下载英语语言包(如果是其他语言则下载其他包了),不过en现在最好用全称en_core_web_sm,这一步也可以先下载tar再pip install en_core_web_md-2.2.5.tar.gz(但是注意把文件放对路径)。 然后测试下代码:
