如果尝试在numpy中创建具有大量维的数组,则会引发异常:
In [1]: import numpy as np In [2]: a = np.zeros((1,) * 33) --------------------------------------------------------------------------- ValueError Traceback (most recent call last) <ipython-input-2-32dc30f6e439> in <module>() ----> 1 a = np.zeros((1,) * 33) ValueError: sequence too large; must be smaller than 32
有没有简单的解决方法?
为什么numpy不允许创建此类数组的原因是什么?
从NumPy源代码:
/* * There are several places in the code where an array of dimensions * is allocated statically. This is the size of that static * allocation. * * The array creation itself could have arbitrary dimensions but all * the places where static allocation is used would need to be changed * to dynamic (including inside of several structures) */ #define NPY_MAXDIMS 32 #define NPY_MAXARGS 32
您可以更改这些定义,并从源代码构建适合您需求的不兼容版本。
