Describe the issue: When converting a numpy array containing numpy.nan to type int, the numpy.nan are replaced by either -9223372036854775808 or 0 depending on the computer. numpy.nan is replaced by -9223372036854775808 on a Mac Pro (201...
使用numpy中的astype()方法可以实现,示例如下: x Out[20]: array([[5.,4.], [4.,4.33333333], [3.66666667,4.5]]) x.astype(int) Out[21]: array([[5,4], [4,4], [3,4]]) 参考:http://stackoverflow.com/questions/10873824/how-to-convert-2d-float-numpy-array-to-2d-int-numpy-array...

s_int = s.to_numeric(errors='coerce') 在上面的例子中,我们首先将NumPy数组转换为pandas Series对象,然后使用to_numeric()方法将字符串转换为整数类型。errors='coerce'参数表示在转换过程中遇到无法转换的值时将其设置为NaN(不是数字)。你可以根据需要进一步处理这些NaN值。总结:解决“TypeError: can’t conver...
