Program raised StopIteration error when using pattern library on Python

I want to use suggest function from pattern library in Python but I encountered an error.

I expected to see the output but it raised StopIteration error.

My code:

from pattern.en import sentiment, suggest

print(sentiment("What a mess day!"))
print(suggest("Aerplane"))

Terminal output:

(-0.21875, 0.175)
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/pattern/text/__init__.py", line 609, in _read
    raise StopIteration
StopIteration
The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Users/umutsatir/Desktop/nda/sentiment.py", line 4, in <module>
    print(suggest("Aerplane"))
          ^^^^^^^^^^^^^^^^^^^

    for x in _read(self._path):
RuntimeError: generator raised StopIteration

I am newbie at StackOverFlow. If any data is missing, please let me know. Thanks!

(I am posting this as an answer to allow me to nicely format the code suggestions.)

Try editing your /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/pattern/text/__init__.py file. Find the definition of the _read method. For me this is line 588. Then wrap the

for i, line in enumerate(f):
    ...

block with a try/except like

try:
    for i, line in enumerate(f):
        ...
except StopIteration:
    return
