python-3.x - Python3：欧。函数只有关键字参数或注释，使用可以支持它们的 inspect.signature() API

Question

我正在使用 python 3.8 将大型 CSV 文件导入具有 odo 函数的 mysql 表中。

@profilehooks.timecall
def useOdo(table_name, uri):
    odo.odo('tmp.csv', '%s::%s' % (uri, table_name))

这会产生以下错误。

Traceback (most recent call last):

Coudn找不到太多关于这个。任何人都可以帮忙吗？
