07_04_random_forest in baseball_fantasy

[AntoineLB13]

Hello nathan,
in 07_04_random_forest, I am experiencing problems.
First of all, the DATA100 line does not take all the necessary directories into account. It is './data/100-game-sample/' instead of starting at the directory of Users/.
and, the line dfp = (pd.read_csv(path.join(DATA100, 'pitches.csv'))
.query("pitch_type.notnull() & pitch_type not in ('FO', 'PO')")) has an error to it: TypeError: unhashable type: 'numpy.ndarray'
I tried to fix it but I am no pro.
Wondering if you can tell me why it does not work like all the other files of every other chapter.

Great book by the way

Thanks for letting me know about this. I just updated the DATA100 directory in that file to be more consistent with the rest of the files, you can try grabbing them again.

As for me, the line you reference:

dfp = (pd.read_csv(path.join(DATA100, 'pitches.csv'))
.query("pitch_type.notnull() & pitch_type not in ('FO', 'PO')")

works (I even copied and pasted what you had here), so not sure what's going on. Maybe try it with the updated DATA100 and let me know if it still doesn't work?

Ok thanks This is what I used instead and I believe it works dfp = (pd.read_csv(path.join(DATA100, 'pitches.csv')) .query("pitch_type not in ('FO', 'PO')")) dfp = dfp.loc[dfp['pitch_type'].notnull()] I am getting around 85-86 % when I run the test['correct'].mean()

Sometimes you can also specify engine='python' too. Like:

dfp = (pd.read_csv(path.join(DATA100, 'pitches.csv'))
.query("pitch_type.notnull() & pitch_type not in ('FO', 'PO')", engine='python')

But glad it's working now.

Hello, for the web scraping section, I feel like it only works for your specific baseball-almanac webpage and not for anything else. Do you have other examples of web scraping on other sites to make us understand more the web scraping of various html setups of websites? Thank you and have a good day
