如何从该笔记本中访问Jupyter笔记本的名称

我想从该Juypyter笔记本中访问Jupyter笔记本的名称。我需要这个名称，因为我想导入一个包含一些辅助代码的小.py文件。此heatmap_axes.py文件在笔记本上的文件夹外面。 So I am using an approach from here.这种方法要求我使用__文件__访问当前文件的名称，但这似乎在Jupyter笔记本中不起作用。

那是代码：

script_dir = os.path.dirname(__file__)
module_dir = os.path.join(script_dir, '..')
sys.path.append(module_dir)
from heatmap_axes import set_date_ticks

当我运行代码时，我会收到一个错误：

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_2232/3919301704.py in <module>
     21 from distutils.spawn import find_executable
     22 
---> 23 script_dir = os.path.dirname(__file__)
     24 module_dir = os.path.join(script_dir, '..')
     25 sys.path.append(module_dir)

NameError: name '__file__' is not defined

好的，我可以自己编写笔记本的名称，但是我需要在几个笔记本中导入此助手.py文件。，所以我想要一个自动解决方案。使用笔记本在文件夹中复制.py也不是一个选项代码>这些目录中的文件。

也就是说，文件结构的外观：

heatmap_axes.py
nb01\
   <somenotebookname>.ipynb
    ...
nb02\
    <somenotebookname>.ipynb
    ...
nb03\
...

I want to access the name of a jupyter notebook from within that juypyter notebook.
I need the name, because I want to import a small .py file containing some helper code. This heatmap_axes.py file is outside the folder, where the notebook is. So I am using an approach from here. This approach requires my to access the name of the current file with __file__, but that doesn't seem to work in the jupyter notebook.

That is the code:

script_dir = os.path.dirname(__file__)
module_dir = os.path.join(script_dir, '..')
sys.path.append(module_dir)
from heatmap_axes import set_date_ticks

When I run the code, I get an error:

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_2232/3919301704.py in <module>
     21 from distutils.spawn import find_executable
     22 
---> 23 script_dir = os.path.dirname(__file__)
     24 module_dir = os.path.join(script_dir, '..')
     25 sys.path.append(module_dir)

NameError: name '__file__' is not defined

OK, I could write the name of the notebook on my own, but I need to import this helper .py file in several notebooks, so I want an automated solution. Copying the .py file inside the folder with the notebooks also is not an option, because I have many directories containg notebooks, and I don't want to have to copy this .py file in each of these directories.

That is, what the file-structure looks like:

heatmap_axes.py
nb01\
   <somenotebookname>.ipynb
    ...
nb02\
    <somenotebookname>.ipynb
    ...
nb03\
...

解决：

script_dir = os.path.abspath('')

找到。

Solved:

script_dir = os.path.abspath('')

这在我基于 JupyterLab 的 Domo Jupyter 环境中对我有用：

from IPython import get_ipython
import os

ip = get_ipython()

this_notebook_path = ip.user_ns['__session__']
print('Notebook file plus path : ' + this_notebook_path)

this_notebook_name = os.path.basename(this_notebook_path)
print('Notebook file without path : ' + this_notebook_name)

This worked for me in my Domo Jupyter environment which is based on JupyterLab:

from IPython import get_ipython
import os

ip = get_ipython()

this_notebook_path = ip.user_ns['__session__']
print('Notebook file plus path : ' + this_notebook_path)

this_notebook_name = os.path.basename(this_notebook_path)
print('Notebook file without path : ' + this_notebook_name)
