error message using fmin

[quan long]

Hello all, 

First time using hyperopt fmin. I have been trying to figure out this error for hours:

Very standard code: 

spark_trials = SparkTrials(

parallelism = 8

)

with mlflow.start_run(run_name='gb_hyperopt') as run:

  # Use hyperopt to find the parameters yielding the highest AUC

  best_params = fmin(

    fn=train_model, 

    space=search_space, 

    algo=tpe.suggest, 

    max_evals=32,

    trials=spark_trials)

error message says: 

TypeError: __init__() got an unexpected keyword argument 'postfix'

Details are attached...

Any hint please ?

Thanks a lot,

Quan
