Since I cannot download data from train_October_9_2012.csv(because unknown error), I recreated small version of it:

After training with this data I cannot inference using python nor rust
If I use python, following error occurs:

Traceback (most recent call last):
  File "src/python_alternative.py", line 39, in <module>
    df_tiny = df_tiny[
  File "/home/user/.local/lib/python3.8/site-packages/pandas/core/frame.py", line 3464, in getitem
    indexer = self.loc._get_listlike_indexer(key, axis=1)[1]
  File "/home/user/.local/lib/python3.8/site-packages/pandas/core/indexing.py", line 1314, in _get_listlike_indexer

  File "/home/user/.local/lib/python3.8/site-packages/pandas/core/indexing.py", line 1374, in _validate_read_indexer
    raise KeyError(f"None of [{key}] are in the [{axis_name}]")
KeyError: "None of [Index(['Title', 'BodyMarkdown', 'OpenStatus'], dtype='object')] are in the [columns]"

If I use rust:

thread 'main' panicked at 'called Option::unwrap() on a None value', src/main.rs:97:55

BTW, if I use windows, error occur even earlier, but it is different

Issue was caused by wrong medium.csv file, which wasn't copied fully
