Re: cerebro.optstrategy() failing with maxcpus > 1 (pickle error)
I am trying to run the sample code provided on backtrader quickstart guide for optimization. I only get the optimization output if I specify:
cerebro.run(maxcpus=1)Any other value of maxcpus resulted in no log print. Omitting maxcpus parameter also resulted in no output. I have tried the following values:
2
3
4
NonePython 3.8.2
Backtrader 1.9.74.123
