我试图在笔记本(Python)中运行Jupyter笔记本(R)。使用命令:
--replicas n
调用Noteook并运行它,但会出现Python错误。正在调用的笔记本(DESeq2 Analysis.ipynb)应该与R内核一起运行。当我独立运行时,DESeq2 Analysis.ipynb与R内核运行良好。似乎正在发生的事情是使用Python 3内核运行的调用笔记本调用DESeq2 Analysis.ipynb并尝试使用Python 3内核而不是R内核运行代码。
使用%run命令时有没有办法指定内核?
答案 0 :(得分:0)
从@Louise Davies answer到Can Jupyter run a separate R notebook from within a Python notebook?
我不认为你可以在执行当前内核中的文件时使用
%run
magic命令。Nbconvert有一个执行API,允许您执行笔记本。因此,您可以创建一个shell脚本来执行所有笔记本,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
由于您的笔记本电脑不需要共享状态,因此这应该没问题。或者,如果您真的想在笔记本中使用它,可以使用execute 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,这只是从nbconvert执行API文档中复制的示例:link
