Python 区域统计脚本：尝试安装 rioxarray 后出现问题

Question

我有一个用于计算区域统计数据（中位数）的脚本，但现在我得到了 AttributeError：'DatasetReader' 对象没有属性 'affine'。这是我的代码：

with rasterio.open(f'{project_data}/ras.tif') as raster:
    array = raster.read(1)
    affine = raster.affine
    stat = zonal_stats(f'{project_data}/Lila.shp', array, affine=affine,
        stats=['median'], geojson_out=True)

    result = {"type": "FeatureCollection", "features": stat}


    outname = f'{project_data}/files/Lala_test.geojson'
    with open(outname, 'w') as outfile:
        json.dump(result, outfile)

我昨天尝试用 Anaconda 安装 rioxarray 但没有成功，我使用的是虚拟 conda - 环境 (Python 3.8 Interpreter)，这可能是问题所在吗？如果是，我该如何解决？我在 windows 10...

affine 已弃用。 transform 现在接受 GDAL 和仿射样式转换。

从 迁移到 Rasterio 1.0 affine.Affine() 与 GDAL 风格的地理变换:

https://rasterio.readthedocs.io/en/latest/topics/migrating-to-v1.html

Since the above changes, several functions have been added to Rasterio that accept a transform argument. Rather than add an affine argument to each, the transform argument could be either an Affine() object or a GDAL geotransform, the latter issuing the same deprecation warning.

The original plan was to remove the affine argument + property, and assume that the object passed to transform is an Affine(). However, after further discussion it was determined that since Affine() and GDAL geotransforms are both 6 element tuples users may experience unexplained errors and outputs, so an exception is raised instead to better highlight the error.
