TabPy TypeError％d格式需要一个数字，而不是str，后跟没有返回值

I have just started to work with TabPy on 10.13.2. I used the conda pymysql packages (pymysql and PyMySQL-0.8.0-py2.7.egg-info) and placed them in the site-packages for anaconda, so that Tableau would be able to connect to the db, retrieve the dataset and hold in a calculated field.I have just started to work with TabPy on 10.13
