Crash when calculating Alpha158 #2126
Description
❓ Questions and Help
When I calculate the Alpha158 factors, the system always freezes, then the screen goes black, and I have to force a shutdown. This happens even when calculating factors for just a few stocks over a couple of days. What could be the reason? Here is my code:
`stock_list = ["SH000001", "SZ399001", "SH000300"]
start_time = "2018-12-26"
end_time = "2018-12-27"
handler = Alpha158(
instruments=instruments,
start_time=start_time,
end_time=end_time
)`
