ValueError: Big-endian buffer not supported on little-endian compiler 要处理此问题,您应该在将底层 NumPy 数组传递给Series或DataFrame构造函数之前将其转换为本机系统字节顺序,如下所示: In [49]: x = np.array(list(range(10)), ">i4") # big endian In [50]: newx = x.byteswap().view(x....
An alternate approach is that of using masked arrays. A masked array is an array of data with an associated booleanmaskdenoting whether each value should be consideredNAor not. I am personally not in love with this approach as I feel that overall it places a fairly heavy burden on the user...
