AttributeError:无法从'/app/.heroku/python/bin/gunicorn'>:Django项目中获取<module'\uuuu main\uuuu'上的属性'myfunctionname'

Question

我在Django应用程序中使用自定义模块，在Heroku中部署时遇到问题

这是我的自定义模块defs.py的内容：

    import numpy as np
    def myfunctionname(x):
            return np.log(x + 1)

此文件正在manage.py中作为

from defspack.defs import myfunctionname

程序文件：

web gunicorn appname.wsgi --log-file -
