在 python jupyter 中发布导入模块

Question

你好，我正在尝试将 geopandas 导入我的脚本

import pandas as pd
import geopandas as gpd
from shapely.geometry import Point

#handling txt
#remove 'lat=' and 'long=' then type change from object to float to make point.
df = pd.read_csv('latlong.txt', header=None, names = ['lat','long', 'name','description'])

df['lat'] = df['lat'].str.replace('lat=', '')
df['long'] = df['long'].str.replace('long=', '')

df['lat'] = df['lat'].astype(float)
df['long'] = df['long'].astype(float)

#make point geometry
df['geometry'] = df.apply(lambda row: Point(low['long'], low['lat']), axis=1) #long is X, lat is Y

#change df to gdf
gdf = gpd.GeoDataFrame(df, geometry = 'geometry', crs='EPSG:4326')  #epsg4326 is WGS84

但是当我尝试在 jupyter notebook 中运行这个时，使用来自以下步骤的 conda 环境：https://medium.com/@nrk25693/how-to-add-your-conda-environment-to-your-jupyter-notebook-in-just-4-steps-abeab8b8d084

我收到以下错误：

ImportError                               Traceback (most recent call last)

ImportError: Unable to import required dependencies:
numpy: 

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.9 from "C:\Users\User\.conda\envs\geojsongen\python.exe"
  * The NumPy version is: "1.21.2"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.

我使用以下命令在此环境中安装了 geopandas：
conda install -c conda-forge geopandas

有人可以告诉我如何修复这些错误吗？感谢任何帮助，谢谢！！

编辑：我尝试了这个 pip install --upgrade --force-reinstall numpy，感谢@krmogi，但现在我得到了这个错误，它看起来像我的 geopandas 安装有问题？ :

如您的回溯所示，您的问题出现在这里

----> 1 import pandas as pd

确保您已安装 pandas。

pip install pandas

它还说 numpy C 扩展失败。同时安装 numpy：

pip install numpy

安装时，请确保您也安装了其他模块。

如果您仍然遇到同样的错误，可能是 setuptools 没有正确安装。这样做：

pip uninstall -y numpy
pip uninstall -y setuptools
pip install setuptools
pip install numpy

如果你还是没有运气，试试这个：

pip install --upgrade --force-reinstall numpy
