2、int、unsigned int 、short int、unsigned short 、long int 、unsigned long 、float、double、long double类型的sizeof 在ANSI C中没有具体规定,大小依赖于实现,一般可能分别为2、2、2、2、4、4、4、8、10。 3、当操作数是指针时,sizeof依赖于编译器。例如Micros

sys.maxint()方法不再支持Python 3作为整数。如果我们使用这个方法或常量,我们将得到下面的AttributeError: module 'sys' has no attribute 'maxint'。 为了在Python 3.0中克服这个问题,引入了另一个常量sys.maxsize,我们知道它会返回Py_ssize_t的最大值。在Python 3中,int和long int是合并的。

it shows that usage is still about 200MB (which is roughly the original dataset size, rather than the Kernel matrix size). Looks like the issue is in svm.cpp, where the cache size is set to(long int) cache_size*(1<<20). I suspect this overflows for cases where cache_size>2000. ...

Characterization of the size and material properties of particles in liquid suspensions is in very high demand, for example, in the analysis of colloidal samples or of bodily fluids such as urine or blood plasma. However, existing methods are limited in
