hyperopt 中 Trials() 对象的内容

Question

此查询指的是将试验用作 fmin 中的参数。

trials = Trials()
best = fmin(objective, space=hp.uniform('x', -10, 10), algo=tpe.suggest,
    max_evals=100, trials=trials)

文档 ( https://github.com/hyperopt/hyperopt/wiki/FMin ) 指出，试验对象获得了诸如trial.trials、trial.results、trial.losses()和trial.statuses() 之类的列表。

但是，我看到了文档中没有提到的trials.best_trial和trial.trial_attachments等用法。

现在我想知道如何获得试验对象的所有内容的列表？对象类型是hyperopt.base.Trials。

Answer 1

根据Hyperopt 代码：“试验 - 至少包括子文档的文档列表

['spec'] - the specification of hyper-parameters for a job
['result'] - the result of Domain.evaluate(). Typically includes:
    ['status'] - one of the STATUS_STRINGS
    ['loss'] - real-valued scalar that hyperopt is trying to minimize
['idxs'] - compressed representation of spec
['vals'] - compressed representation of spec
['tid'] - trial id (unique in Trials list)`
