ArcGIS 显示错误名称“np”；没有定义

Question

我已经在Python中安装了arcgis库。使用的安装命令：-

pip install arcgis

但是，当我尝试从 arcgis 导入以下内容时，我面临以下问题：-

from arcgis.learn import prepare_data
from arcgis.learn.text import EntityRecognizer

错误：

NameError                                 Traceback (most recent call last)

我已卸载 arcgis，然后再次安装它。我还卸载并安装了 numpy 并再次导入为 np 。

但问题仍然存在。
