How to use it on gogle colab?

[rrfaria]

What I did:
I followed readme and added initial code but it isn't works

!pip install --no-deps git+git://github.com/Heerozh/spectre.git
!pip install pytorch torchvision torchaudio
!pip install pyarrow pandas tqdm plotly requests

by default cudatoolkit is already installed on colab
then I imported the code:

from spectre.data import YahooDownloader
YahooDownloader.ingest(start_date="2011", save_to="/content/prices/yahoo", symbols=None, skip_exists=True)

and the errors shows:

Download prices from yahoo...
---------------------------------------------------------------------------

      1 from spectre.data import YahooDownloader

--> 547             raise ValueError("No tables found")
    548 
    549         result = []

ValueError: No tables found

if I use:

YahooDownloader.ingest(start_date="2011", save_to="/content/prices/yahoo", symbols=['EURUSD=X'], skip_exists=True)

ERROR:

problem is downloading data from Yahoo, not related to colab.
It seems that Yahoo changed his API.

Yahoo often changes his methods to prevent others from downloading, you better find other ways to get data.
