我正在按照 Krish Naik 的 YouTube 频道上的葡萄酒质量预测端到端 ML 项目所示的流程来执行航班票价预测项目。
我在 03_data_transformation.ipynb:
上运行此数据转换管道单元try:
config = ConfigurationManager()
data_transformation_config = config.get_data_transformation_config()
data_transformation = DataTransformation(config=data_transformation_config)
# data_transformation.train_test_spliting()
# New Line
data_transformation.initiate_data_transformation()
except Exception as e:
raise e
我收到此错误：
TypeError: convert_to_minutes() takes 1 positional argument but 2 were given
这是回溯：
