我使用 pip 安装tensorflow，但是tensorflow import 不起作用

Question

我已经安装了tensorflow，如下所示：pip3.8 install tensorflow（我使用pip3.8命令，因为我在我的EC2实例上安装了多个python版本）。当我这样做时，我会得到以下输出：

Defaulting to user installation because normal site-packages is not writeable
Collecting tensorflow
  Downloading tensorflow-2.8.0-cp38-cp38-manylinux2010_x86_64.whl (497.6 MB)
     |████████████████████████████████| 497.6 MB 37.1 MB/s eta 0:00:01Killed

每次安装时都会得到相同的输出。我有一个 django 项目在我的本地计算机上运行得很好，但是当我在 EC2 实例上使用 python3.8 manage.py runserver --insecure 测试它时

： 8 冻结 尝试 pip3.8 install tensorflow 几次后，我得到：

asgiref==3.5.0
Django==3.2.5
numpy==1.22.2
protobuf==3.19.4
pytz==2021.3
sqlparse==0.4.2
tensorflow-hub==0.12.0

当我运行 pip3.8 --version 时，我得到：

pip 21.1.1 from /usr/local/lib/python3.8/site-packages/pip (python 3.8)

我也尝试过 sudo pip3.8安装tensorflow，它给出了与我在没有sudo的情况下运行相同命令时相同的输出。

我正在使用 python 3.8.12 （我已经从源代码手动安装了它）。

有谁知道我该如何解决这个问题？
