contravariance covariance invariance typevar
Only the invariant culture is supported in globalization-invariant mode. See https://aka.ms/GlobalizationInvariantMode for more information
错误信息：全球化不变模式只支持不变文化。看见https://aka.ms/GlobalizationInvariantMode了解更多信息 修改引用配置即可：<InvariantGlobalization>true</InvariantGlobalization> 改为false Only the ......
python中的泛型使用TypeVar
1.引入为什么需要TypeVar PEP484的作者希望借助typing模块引入类型提示，不改动语言的其它部分。通过精巧的元编程技术，让类支持[]运算不成问题。但是方括号内的T变量必须在某处定义，否则要大范围改动python解释器才能让泛型支持特殊的[]表示法。 鉴于此，我们增加了typing.Ty ......
Is every covariance matrix positive definite?
Well, to understand why the covariance matrix of a population is always positive semi-definite, notice that: \[\sum_{i, j=1}^n y_i \cdot y_j \cdot \op ......

2023-11-22 Invariant Violation: [app.model] namespace should be unique ==》模块命名相同导致报错，修改名称即可
如上图，报错原因：存在多个名为demoDataSource的模块名称导致报错 解决方案：修改模块名称即可，把demoDataSource改为demoDataSource2就不会报错了 扩展：该问题是由rudex引起的，redex要求数据模型(models)命名（namespace）必须不同，否则在注 ......

关于equivariance（equivariant） 和 invariance（invariant）
关于「equivariance：等变性」和「invariance：不变性」这两个概念，我的理解是 equivariance：输入改变，输出对应的改变 invariance：输入改变，输出不发生变化 从字面也可以理解出这一层意思。 但是在我看文献的过程中，我发现有的文章的说法是反的，比如 ON THE ......
