我认为您不能以%run
这种方式使用魔术命令,因为它在当前内核中执行文件。
Nbconvert 有一个执行 API,允许您执行笔记本。因此,您可以创建一个执行所有笔记本的 shell 脚本,如下所示:
#!/bin/bash
jupyter nbconvert --to notebook --execute 1_py3.ipynb
jupyter nbconvert --to notebook --execute 2_py3.ipynb
jupyter nbconvert --to notebook --execute 3_py3.ipynb
jupyter nbconvert --to notebook --execute 4_R.ipynb
由于您的笔记本不需要共享状态,这应该没问题。或者,如果您真的想在笔记本中执行此操作,您可以使用执行 Python API 从笔记本中调用 nbconvert。
import nbformat
from nbconvert.preprocessors import ExecutePreprocessor
with open("1_py3.ipynb") as f1, open("2_py3.ipynb") as f2, open("3_py3.ipynb") as f3, open("4_R.ipynb") as f4:
nb1 = nbformat.read(f1, as_version=4)
nb2 = nbformat.read(f2, as_version=4)
nb3 = nbformat.read(f3, as_version=4)
nb4 = nbformat.read(f4, as_version=4)
ep_python = ExecutePreprocessor(timeout=600, kernel_name='python3')
#Use jupyter kernelspec list to find out what the kernel is called on your system
ep_R = ExecutePreprocessor(timeout=600, kernel_name='ir')
# path specifies which folder to execute the notebooks in, so set it to the one that you need so your file path references are correct
ep_python.preprocess(nb1, {'metadata': {'path': 'notebooks/'}})
ep_python.preprocess(nb2, {'metadata': {'path': 'notebooks/'}})
ep_python.preprocess(nb3, {'metadata': {'path': 'notebooks/'}})
ep_R.preprocess(nb4, {'metadata': {'path': 'notebooks/'}})
with open("1_py3.ipynb", "wt") as f1, open("2_py3.ipynb", "wt") as f2, open("3_py3.ipynb", "wt") as f3, open("4_R.ipynb", "wt") as f4:
nbformat.write(nb1, f1)
nbformat.write(nb2, f2)
nbformat.write(nb3, f3)
nbformat.write(nb4, f4)
请注意,这几乎只是从 nbconvert 执行 API 文档复制的示例: 链接
