Getting the error: AttributeError: function 'GetOutputTypeStr' not found

[sauvikd]

I have two simple codes to test the PIML:

CODE 1:

from piml import Experiment
from piml.models import GAMINetRegressor

"""## Load and Prepare Data"""
exp = Experiment()
exp.data_loader(data="BikeSharing")
exp.data_summary(feature_exclude=["yr", "mnth", "temp"])        # , silent=True
exp.data_prepare(target="cnt", task_type="regression")

# In[]
exp.model_train(model=GAMINetRegressor())

CODE 2:

# LOAD DATA AND BASIC PREVIEW
# ---------------------------------------------------------------------------------------------
df = pd.read_csv(r"H:\WORK\ML Project (EBM)\Dataset\CO2_MMP.csv")
print("First few rows of the data:")
print(df.head())

# In[]
input_features = ['T', 'C1', 'C2-C6', 'Vol', 'Int', 'C7+', 'MWC5+']
output = ['MMP']
X_train, X_test, y_train, y_test = train_test_split(df[input_features], df[output], test_size = 0.2, random_state = 42)

# In[]
gaminet_param_grid = {    }
gaminet_kf = KFold(n_splits=10, shuffle=True, random_state = 42)
gaminet_model = GAMINetRegressor(random_state = 42)   # GAMINet: generalized additive model with structured pairwise interactions network

# HP Tuning(Grid, kfold, model)
grid_search = GridSearchCV(gaminet_model, gaminet_param_grid, cv=gaminet_kf, scoring='neg_mean_squared_error', n_jobs=-1, error_score='raise')
grid_search.fit(X_train, y_train)

# Best parameters and model
best_gaminet_params = grid_search.best_params_                # Optimal parameters
best_gaminet_model = grid_search.best_estimator_               # Best GAMINet Model

In both the codes I'm getting the same error as below. AttributeError: function 'GetOutputTypeStr' not found

I couldnt figure out the reason behind it. I have also pasted the full error message from both codes. Can you provide a solution?
