FutureWarning：与 'None' 错误的比较

Question

我是 Python 的新手，我在互联网上搜索过帮助，但没有解决我眼前的问题，所以希望得到任何反馈。有谁知道为什么我会收到此警告？

我已经下载并尝试使用开源模块 (CloudRasterizer.py) 从 EcosynthAerial 工具箱 Windows 编辑点云 (LiDAR/spatial 数据)。在模块中有一个 class 'CloudRasterizer'，我将从中调用特定的方法。但是，每当我尝试启动 class 时，我都会收到以下警告，并且无法通过此...

In the Python command line

EastAreaTest = np.loadtxt("C:\....TestFile.txt", use cols=(0,1,2,3,4,5))  
EastAreaArray = np.array(EastAreaTest)  
Import CloudRasterizer  
from CloudRasterizer import CloudRasterizer  
RasterizedTest = CloudRasterizer(EastAreaArray)

CloudRasterizer.py:290: FutureWarning: comparison to 'None' will result in an elementwise object comparison in the future. If (xyzrgb_array==None): get_aoi time:0.0 subset_cloud_ array time: 0.0 get_aoi time: 0.015 cloud_to_grid time: 0.015

这是模块代码的开头：

_all__ = ['CloudRasterizer']

    import time

    import numpy as np
    import pylab as pl
    import scipy.stats as stats


    class CloudRasterizer(object):
    """
         CloudRasterizer Class for processing Point Cloud and enabling 2D analysis

    :param np.array xyzrgb_array: XYZRGB numpy array
    :param int resolution: (Optional) grid size relative to units of
        point cloud (assumed to be meters)
    :pararm list aoi: (Optional) [xMin, xMax, yMin, yMax, zMin, zMax]

    :var int resolution: grid size relative to units of point cloud
    :var np.array cloud_array: points in given AOI
    :var int xMin:
    :var int yMin:
    :var int zMin:
    :var np.array grid: 2D grid of arrays filled with XYZRGB points

    """
    def __init__(self, xyzrgb_array, resolution=1):
        """

        """
        self.aoi = self.get_aoi(xyzrgb_array=xyzrgb_array)
        self.resolution = resolution
        self.cloud_array = self.subset_cloud_array(xyzrgb_array, self.aoi)
        self.grid = self.cloud_to_grid(self.cloud_array, resolution)

如果有帮助，这是我导入 CloudRasterizer 时的当前目录（CloudRasterizer.py 在 post 进程文件夹中）：

C:\Users\MillerEF\Documents\Miniconda2\Lib\site-packages\ecosynth\postprocess

非常感谢您的帮助！

在模块的第 290 行，将 if (xyzrgb_array==None): 更改为 if (xyzrgb_array is None):。
