Hello all!
I am not a programmer and my knowledge is very poor on this topic.
My task is to upload historical data from Yahoo Finance.
For this I use Python and specifically the yf.download library
The code is correct, since everything works for my teacher, BUT! he uses a Windows PC, I have a MacBook Pro (M1 2020 8 GB RAM).
It is necessary to upload data on 4933 stocks, and when it comes to about 2000, the process stops and does not go any further.
RuntimeError: can't start new thread occurs
I think that the problem is in the computer (it is logical to assume).
If anyone knows how to get around this (without changing the computer), please write. I'll be very grateful.
code below:
nasdaq_stocks = yf.download(tickers = nasdaq_tickers, period = 'max', interval = '1d', group_by = 'ticker')
result:
[ 0% ] 13 of 4933 completed
