How to remove python assertion when compiling in cython?

阅读更多关于 How to remove python assertion when compiling in cython?

问题 so, here is my problem: I code in python, but I need to improve performance in some part of my code that are too slow. A good(and easy) solution seems to be using cython; I tried it and got good results. The issue is that I use assert statement in my python code. Before using cython, I could compile my python code with the -OO option, so that I can deliver a version not executing any assertion test, and still have the assert for debug. But the files that are compiled in cython seems to always

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 很不错的一篇文章，很多不明白的地方在此讲的很清楚，很完整，主要是MFC的宏定义了．站长黑森林推荐！ AND_CATCHAND_CATCH AND_CATCH(exception_class,exception _object_point_name) 说明：定义一个代码块，它用于获取废除当前TRY块中的附加异常类型。使用CATCH宏以获得一个异常类型，然后使用AND_CATCH宏获得随后的异常处理代码可以访问异常对象（若合适的话)已得到关于异常的特别原因的更多消息。在AND_CATCH块中调用THROW_LAST宏以便把处理过程移到下个外部异常框架。AND_CATCH可标记CATCH或AND_CATCH块的末尾。注释： AND_CATCH块被定义成为一个C++作用域（由花括号来描述）。若用户在此作用域定义变量，那么记住他们只在此作用域中可以访问。他也用于exception_object_pointer_name变量。 ASSERT ASSERT(booleanExpression) 说明：计算变量的值。如果结构的值为0，那么此宏便打印一个诊断消息并且成讯运行失败。如果条件为非0，那么什么也不做。诊断消息的形式为： assertion failed in file in line 其中name是元文件名

python script running with mpirun not stopping if assert on processor 0 fails

问题 I have a python script with a set of operations done in parallel, with the library mpi4py. At the end of the operations the processor with rank 0 executes an assert test. If the assert fails, the process should stop and the program terminate. However, the program doesn't exit and this I guess is because the other processors are holding. How to make the program ending the execution if the assert fails? I run things with a command like: mpirun -np 10 python myscript.py and then I have a line in

Date range validation with Symfony2

阅读更多关于 Date range validation with Symfony2

问题 I want to add a constraint with annotation in Symfony for a date falls within the range, but this range can not be specified explicitly with min. and max. The year should be between the current year (by subtracting the current year or number) and the minimum indicated. For example, if I type a date now must be between 2010/1960, but 2010 should be obtained from the current year-10. This can be done in any way in Symfony? 回答1: Yes it is possible, you should create a custom validation

问题 I am using JUnit 4.12 and this is my current understanding of the following APIs I use frequently: assumeTrue: if expression evaluates to false, test will halt and be ignored assertTrue: if condition is false, throws an AssertionError assertEquals: if they are not equal, an AssertionError is thrown with the given message assertNotNull: if it is null, throws an AssertionError However, I am unable to get clarity on couple of things: my understanding is that only for assumeTrue, the tests will
