Describe the bug `from hyperopt import hp from flair.hyperparameter.param_selection import SearchSpace, Parameter

search_space = SearchSpace()

define training hyperparameters

search_space.add(Parameter.EMBEDDINGS, hp.choice, options=[document_embeddings]) search_space.add(Parameter.LEARNING_RATE, hp.choice, options=[0.01, 0.05, 0.1, 0.15, 0.2]) search_space.add(Parameter.MINI_BATCH_SIZE, hp.choice, options=[8, 16, 32, 64, 128, 256])

define transformer embedding hyperparameters

search_space.add(Parameter.TRANSFORMER_MODEL, hp.choice, options=['gru', `'lstm'])``

`from flair.hyperparameter.param_selection import TextClassifierParamSelector, OptimizationValue

what label do we want to predict?

label_type = 'nation'

create the parameter selector

param_selector = TextClassifierParamSelector( corpus, label_type, False, 'resources/result', max_epochs=50, fine_tune=True, training_runs=3, optimization_value=OptimizationValue.DEV_SCORE )

start the optimization

param_selector.optimize(search_space, max_evals=100)`
