次のPythonコードでエラーが発生します。私はスクリプトから実行しています。私はPython 2.7.12を使用しています。Pythonスクリプトの実行中にエラーが発生しました。AttributeError: 'NoneType'オブジェクトに 'run_line_magic'属性がありません。
import os
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from IPython import get_ipython
ipython_shell = get_ipython()
get_ipython().run_line_magic('matplotlib', 'inline')
pyとjpy拡張の両方を使用してみました。 matplotlibをインポートする構文を変更しようとしましたが、何も動作しません。
のpythonを実行しているからエラーがiPythonで実行しているから
Traceback (most recent call last):
File "LR.jpy", line 7, in <module>
get_ipython().run_line_magic('matplotlib', 'inline')
AttributeError: 'NoneType' object has no attribute 'run_line_magic'

ipykernelをインストールした後、ビルドエラーで投稿を編集しました。 InteactiveShellインスタンスの登録方法を教えてください。返信いただきありがとうございます。 – Tahlil
