Question

我想将Python脚本的输出从代码重定向到Jupyter Notebook。

我已经找到了可以生成并执行.ipynb文件的nbformat和nbconvert库，因此我只想运行“％run script.py”命令。

这是我要运行的脚本：

<body>
  <div class="container"></div>
  <div class="full even">
    <div class="left">
      <div class="content">
        Edge
      </div>
    </div>
    <div class="right">
      <div class="content">
        Edge
      </div>
    </div>
  </div>
  <div class="full uneven">
    <div class="left">
      <div class="content">
        Edge
      </div>
    </div>
    <div class="right">
      <div class="content">
        Edge
      </div>
    </div>
  </div>
</body>

生成.ipynb：

import numpy as np
import matplotlib.pyplot as plt
def f(x):
    return np.exp(x)
x = np.linspace(-1, 3, 100)
print(x)
plt.plot(x, f(x))

执行.ipynb：

import nbformat as nbf
nb = nbf.v4.new_notebook()
code = """%run -i temp.py"""
nb['cells'] = [nbf.v4.new_code_cell(code)]
fname = 'test.ipynb'
with open(fname, 'w') as f:
    nbf.write(nb, f)

所有文本输出均已生成，但不幸的是，此处未显示图形。这是.ipynb文件：

import nbformat
from nbconvert.preprocessors import ExecutePreprocessor
from nbconvert.preprocessors import CellExecutionError
with open("test.ipynb") as f:
    nb = nbformat.read(f, as_version=4)
ep = ExecutePreprocessor(timeout=6000, kernel_name='python3')
out = ep.preprocess(nb, {'metadata': {'path': '.'}})
with open('executed_notebook.ipynb', mode='wt') as f:
    nbformat.write(nb, f)

在Jupyter Notebook中从其他Python脚本执行Python脚本时如何绘制图形
