Describe the bug(问题描述)
Trying to run a DeepFM model withh only dense features , the models train and save fine but while loading the following exception appears

TypeError: unhashable type: 'list'
To Reproduce(复现步骤)
Steps to reproduce the behavior:
Use only dense features
fixlen_feature_columns= [DenseFeat(feat, 1, ) for feat in dense_features]
dnn_feature_columns = fixlen_feature_columns
linear_feature_columns = fixlen_feature_columns
feature_names = get_feature_names(linear_feature_columns + dnn_feature_columns)
Model
DeepFM(linear_feature_columns,dnn_feature_columns,
l2_reg_linear=1e-05,
l2_reg_dnn=0,
dnn_dropout=0,
dnn_activation='relu',
dnn_use_bn=False,
task='binary')
# save model
Load the saved model
load_model(model_path,custom_objects)
Gives error
