在使用rasterstats包进行栅格统计时遇到错误：AttributeError: module 'numpy' has no attribute 'asscalar'。该问题源于NumPy1.16.0之后移除了asscalar函数。为解决此问题，推荐使用numpy.ndarray.item()替代。其他弃用的函数和属性也进行了说明，包括numpy.unravel_index的dims参数和numpy.histogram的normed参数等。参考NumPy1.16.0 Release Notes以获取更多更新信息。

使用rasterstast包统计栅格，报错：AttributeError: module 'numpy' has no attribute 'asscalar'

原因：NumPy 1.16.0 后就没有asscalar函数了

New deprecations
The type dictionaries numpy.core.typeNA and numpy.core.sctypeNA are deprecated. They were buggy and not documented and will be removed in the 1.18 release. Use`numpy.sctypeDict` instead.

The numpy.asscalar function is deprecated. It is an alias to the more powerful numpy.ndarray.item, not tested, and fails for scalars.

The numpy.set_array_ops and numpy.get_array_ops functions are deprecated. As part of NEP 15, they have been deprecated along with the C-API functions PyArray_SetNumericOps and PyArray_GetNumericOps. Users who wish to override the inner loop functions in built-in ufuncs should use PyUFunc_ReplaceLoopBySignature.

The numpy.unravel_index keyword argument dims is deprecated, use shape instead.

The numpy.histogram normed argument is deprecated. It was deprecated previously, but no warning was issued.

The positive operator (+) applied to non-numerical arrays is deprecated. See below for details.

Passing an iterator to the stack functions is deprecated

使用numpy.ndarray.item（）代替asscalar（）
