ModuleNotFoundError not found in FinRL_PortfolioAllocation_NeurIPS_2020.ipynb

While running 2.3. Import Packages got this error

ModuleNotFoundError                       Traceback (most recent call last)

ModuleNotFoundError: No module named 'finrl.finrl_meta'

Actually, it appears that all of these statements are failing.

from finrl.finrl_meta.preprocessor.yahoodownloader import YahooDownloader
from finrl.finrl_meta.preprocessor.preprocessors import FeatureEngineer, data_split
from finrl.finrl_meta.env_portfolio_allocation.env_portfolio import StockPortfolioEnv
from finrl.finrl_meta.data_processor import DataProcessor
from finrl.finrl_meta.data_processors.processor_yahoofinance import YahooFinanceProcessor

I've tried running this

and changing the from statement to

from finrl_meta.preprocessor.yahoodownloader import YahooDownloader

and

from finrl-meta.preprocessor.yahoodownloader import YahooDownloader

still no luck. 😞

Finally tried

from finrl.meta.preprocessor.yahoodownloader import YahooDownloader

That seemed to have done the trick. 😄

pls change finrl_meta to meta. we revised the folder name.

[ZiyiXia]

Import lines were updated, please check it out.

[zhumingpassional]

if you use finrl-meta library, pls try from meta.data_processor import DataProcessor dp = DataProcessor('yahoofinance', start_date, end_date, time_interval)

Thanks, however, the open in Colab link is still broken. Once fixed, then I can verify the code changes for you.

@zhumingpassional I would, along with everyone else who is trying to use this site, would prefer to have the code fixed verse telling me how to fix it myself (i.e. as a work-a-round).

@ZiyiXia thanks for actually fixing the code, now everyone wins. 👍

To All Contributes - From my experience, new visitors to a repository expect that the getting started documentation is accurate, that all the links actually work, and that all tutorials function correctly - otherwise, they feel the repo/product is not worth anything regardless of how well it might actually work - first impressions are everything. And if the simple things don't work then how can we trust the complicated things to work? We can't, thus most of your visitors will just move on to the next thing.
