when optimizing, always get MemoryError
when I am optimizing, memory is always not enough, it will consume all the memory from 30% to 100%. Finally, it will crash down.
1.the error code is :
multiprocessing.pool.MaybeEncodingError: Error sending result: '[<backtrader.cerebro.OptReturn object at 0x0000026A8C3C9FA0>]'. Reason: 'MemoryError()'
2.backtrader version: 22.214.171.124
3.computer RAM/memory: 16GB
