在 python jupyter 中問題導入模塊

Question

嗨，我正在嘗試將 geopandas 導入到我的腳本中

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

但是當我嘗試在 jupyter notebook 中運行它時，使用以下步驟中的 conda 環境： https ://medium.com/@nrk25693/how-to-add-your-conda-environment-to-your-jupyter-notebook -in-just-4-steps-abeab8b8d084

我收到以下錯誤：

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環境中安裝了 geopandas：
conda install -c conda-forge geopandas

有人可以建議我如何解決這些錯誤嗎？ 任何幫助表示贊賞，謝謝！！

編輯：我試過這個pip install --upgrade --force-reinstall numpy --upgrade pip install --upgrade --force-reinstall numpy ，感謝@krmogi，但現在我收到這個錯誤，它看起來像是我的 geopandas 安裝問題？ ：

Answer 1

如您的回溯所示，您的問題發生在這里

----> 1 import pandas as pd

確保你已經安裝了pandas 。

pip install pandas

它還說numpy C-extensions 失敗了。 也安裝numpy ：

pip install numpy

在此過程中，請確保還安裝了其他模塊。

如果您仍然遇到相同的錯誤，則可能是setuptools安裝不正確。 做這個：

1. pip uninstall -y numpy

2. pip uninstall -y setuptools

3. pip install setuptools

4. pip install numpy

如果您仍然沒有任何運氣，請嘗試以下操作：

pip install --upgrade --force-reinstall numpy
