在pytest中运行jupyter笔记本测试。奥瑟罗

我有一个python测试,它应该运行jupyter笔记本文件并检查是否有错误。 当我运行它时,它返回一个错误: OSError: [Errno 8] Exec format error: './file.ipynb'

有人知道怎么修理这个吗?

我在类似问题中发现的似乎不是我的情况。

我的代码如下:

import os
import subprocess
import tempfile

import nbformat


def _notebook_run(path):
    """Execute a notebook via nbconvert and collect output.
       :returns (parsed nb object, execution errors)
    """
    dirname, __ = os.path.split(path)
    os.chdir(dirname)
    with tempfile.NamedTemporaryFile(suffix=".ipynb") as fout:
        args = [path, fout.name, "nbconvert", "--to", "notebook", "--execute",
          "--ExecutePreprocessor.timeout=60",
          "--output"]
        subprocess.check_call(args)

        fout.seek(0)
        nb = nbformat.read(fout, nbformat.current_nbformat)

    errors = [output for cell in nb.cells if "outputs" in cell
                     for output in cell["outputs"]\
                     if output.output_type == "error"]

    return nb, errors

def test_ipynb():
    nb, errors = _notebook_run('./file.ipynb')
    assert errors == []
