pysyft - 属性错误 : type object 'Tensor' has no attribute 'fft'

Question

当我import syft ，出现以下错误:

AttributeError: type object 'Tensor' has no attribute 'fft'

我关注了 PySyft Doc安装syft。
我试过 import syft在 Ubuntu 18.04 和 Google Colab 环境中。两者都有相同的错误。
Google Colab 上的完整错误信息如下，

import syft as sf

有谁知道如何解决这个问题？谢谢。

Answer 1

pip 安装可与旧 pytorch 一起使用的较低版本的 pysyft。那将解决它。
