在Python编程中,UnboundLocalError是一个运行时错误,它发生在尝试访问一个在当前作用域内未被绑定(即未被赋值)的局部变量时。 错误信息UnboundLocalError: local variable ‘xxx’ referenced before assignment指出变量xxx在赋值之前就...
深度学习的 API 通常是由一群开发人员共同创建的,这些开发人员共同使用行业标准技术和研究工具,但可能并非所有开发人员都可以使用。 而且,通过商业 API 部署的模型通常非常稳定地使用,并提供最新的功能,包括可伸缩性,自定义和准确率。 因此,如果您遇到精度问题(这是深度学习模型生产中的常见情况),那么选择 API 是一...

Filters that are applied to an invalid variable will only be applied if string_if_invalid is set to '' (the empty string). If string_if_invalid is set to any other value, variable filters will be ignored. This behavior is slightly different for the if, for and regroup template tags. ...
Test where branching occurs and thus tailor input to make sure as many different paths through the code are taken. Add an explicit test for any bugs discovered for the tested code. This will make sure that the error does not crop up again if the code is changed in the future. Make ...
