NameError: name 'file' is not defined for IMDP API TSV file

Question

I have been trying to look at the IMDP API through this tsv file https://datasets.imdbws.com/name.basics.tsv.gz". I however I am at a point where I keep on getting this error.

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

----> 1 TsvHandler("https://datasets.imdbws.com/name.basics.tsv.gz")

<ipython-input-4-a2aea9b9f867> in __init__(self, url)
      4         # Example of download url: https://datasets.imdbws.com/title.basics.tsv.gz
      5         self.url = url
----> 6         data_dir = pathlib.Path(__file__).parent.parent.parent.resolve()
      7         self.download_location = os.path.join(data_dir, "data/temp")  # "../../data/temp"
      8         self.filename = self.url.split('/')[-1]

NameError: name '__file__' is not defined

__file__ is only meaningful when you're running a script contained in an actual file. You appear to be pasting code into a Python interactive prompt, which inherently has no filename associated with it. — jasonharper

First, a Jupyter Notebook doesn't have a __file__ variable, see here.

The first solution would be not running this code in a notebook: try creating a Python file (e.g. filename.py), copy the code you want to run into it and then run it using python filename.py.

In the case you must use a Jupyter Notebook, you have two approaches: if you can change the source code, change __file__ to os.path.abspath(''). Otherwise, before calling the TsvHandler class, try defining a global variable named __file__ and assign it to os.path.abspath(''):

__file__ = os.path.abspath('')
TsvHandler("https://datasets.imdbws.com/name.basics.tsv.gz")
