Answer 1

If you are on python 3 and above, just use mysqlclient pip install mysqlclient. It is recommended by django and all the other drivers are bad.

Answer 2

Assuming you are using mysql.connector (I think you are), define your own converter class:

class NumpyMySQLConverter(mysql.connector.conversion.MySQLConverter):
    """ A mysql.connector Converter that handles Numpy types """

    def _float32_to_mysql(self, value):
        return float(value)

    def _float64_to_mysql(self, value):
        return float(value)

    def _int32_to_mysql(self, value):
        return int(value)

    def _int64_to_mysql(self, value):
        return int(value)

config = {
    'user'    : 'user',
    'host'    : 'localhost',
    'password': 'xxx',
    'database': 'db1'
}

conn = mysql.connector.connect(**config)
conn.set_converter_class(NumpyMySQLConverter)

Answer 3

One of your passed values could be of type numpy.float64 which is not recognized by the MySQL connector. Cast it to a genuine python float on populating the dict.
