ts_max(high,20)无法在过滤功能中引用

在输入特征列表中列出ts_max(high,20)和ts_min(low,20),在基础和衍生特征抽取可以成功抽取到这2个值,但是当我调用数据过滤模块的时候,过滤条件写上“
ts_max(high,20)/ts_min(low,20) <1.5
”
结果发现报错并不支持这个条件,不清楚为什么
报错如下:
During handling of the above exception, another exception occurred:
KeyError: 'ts_max'
The above exception was the direct cause of the following exception:
pandas.core.computation.ops.UndefinedVariableError: name 'ts_max' is not defined
During handling of the above exception, another exception occurred:
ValueError: "ts_max" is not a supported function
