Hi!
Please provide the example of your code and data to reproduce this error.
Hi!
Similar to the examples, with some modifications:
# Specify forecast length
len_forecast = 8
task = Task(TaskTypesEnum.ts_forecasting,
TsForecastingParams(forecast_length=len_forecast))
# Got train, test parts, and the entire data
true_values = np.array(df['value'])
train_array = true_values[:-len_forecast]
test_array = true_values[-len_forecast:]
# Data for lagged transformation
train_lagged = InputData(idx=np.arange(0, len(train_array)),
features=train_array,
target=train_array,
task=task,
data_type=DataTypesEnum.ts)
start_forecast = len(train_array)
end_forecast = start_forecast + len_forecast
predict_lagged = InputData(idx=np.arange(start_forecast, end_forecast),
features=train_array,
target=test_array,
task=task,
data_type=DataTypesEnum.ts)
exog_arr = np.array(df['mp'])
exog_train = exog_arr[:-len_forecast]
exog_test = exog_arr[-len_forecast:]
# Data for exog operation
train_exog = InputData(idx=np.arange(0, len(exog_train)),
features=exog_train,
target=train_array,
task=task,
data_type=DataTypesEnum.ts)
start_forecast = len(exog_train)
end_forecast = start_forecast + len_forecast
predict_exog = InputData(idx=np.arange(start_forecast, end_forecast),
features=exog_test,
target=test_array,
task=task,
data_type=DataTypesEnum.ts)
from fedot.core.data.multi_modal import MultiModalData
train_dataset = MultiModalData({
'lagged': train_lagged,
'exog_ts_data_source': train_exog
})
predict_dataset = MultiModalData({
'lagged': predict_lagged,
'exog_ts_data_source': predict_exog
})
# Composer parameters
timeout = datetime.timedelta(minutes=5)
composer_requirements = GPComposerRequirements(
primary=primary_operations,
secondary=secondary_operations,
max_arity=3,
max_depth=8,
pop_size=10,
num_of_generations=20,
crossover_prob=0.8,
mutation_prob=0.8,
timeout=timeout,
cv_folds=2)
If you are using the composer directly, the initial_pipeline should be specified for the multi-modal data (see https://github.com/nccr-itmo/FEDOT/blob/master/cases/multi_modal_rating_prediction.py)
The other way is to use the FEDOT API (see https://github.com/nccr-itmo/FEDOT/blob/master/cases/industrial/multivariate_forecasting.py) instead of direct composer call.
Thanks, these are helpful will check them out!
Hi,
I tried the composer on MultiModalData and it failed, any other options I will be able to use?
