該当のソースコード

import cartopy.crs as ccrs
import matplotlib.pyplot as plt

ax = plt.axes(projection=ccrs.PlateCarree())
ax.coastlines()

plt.show()

試したこと

簡単のため、公式ページに記載されてあるソースコードを引用して、試しに動かしたところ、エラーが発生しました。

DownloadWarning: Downloading: http://naciscdn.org/naturalearth/110m/physical/ne_110m_coastline.zip
の記載の後、1分間程度停止し、その後下のエラーが発生しました。

cartopyは、conda install -c scitools cartopy でインストールしております。

当方初心者で、右も左もわかりません。
ご迷惑をおかけすることがあるかもしれませんが、何卒よろしくお願いいたします

Answer 1

当方の環境でも同一現象が再現しました。
実行時に地図データをサーバからダウンロードしようとしていますが、サーバ自体がダウンしているようですので、どうしようもありません。
時間をおいて試してみるしかないようです。

そうなんですね...!
こちら側ではなく、サーバー側の問題だったとは...。
ご親切にありがとうございました????‍♂️
