ImportError：缺少必需的依赖项 ['numpy']。没有什么帮助

Question

我正在使用 AWS（ubuntu 服务器 18.04）。 当我尝试使用“import numpy”运行代码时，出现错误：

 Traceback (most recent call last):
  File "main.py", line 1, in <module>
    import pandas as pd
  File "/usr/lib/python3/dist-packages/pandas/__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook
    from apport.fileutils import likely_packaged, get_recent_crashes
  File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module>
    from apport.report import Report
  File "/usr/lib/python3/dist-packages/apport/report.py", line 30, in <module>
    import apport.fileutils
  File "/usr/lib/python3/dist-packages/apport/fileutils.py", line 23, in <module>
    from apport.packaging_impl import impl as packaging
  File "/usr/lib/python3/dist-packages/apport/packaging_impl.py", line 24, in <module>
    import apt
  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
Traceback (most recent call last):
  File "main.py", line 1, in <module>
    import pandas as pd
  File "/usr/lib/python3/dist-packages/pandas/__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

我尝试重新安装所有库并已完成所有建议，即here 和here：

sudo -H python3.7 -m pip uninstall numpy
sudo -H python3.7 -m pip uninstall pandas

sudo -H python3.7 -m pip install numpy
sudo -H python3.7 -m pip install pandas

sudo -H python3.7 -m pip install --upgrade numpy
sudo -H python3.7 -m pip install --upgrade pandas

sudo apt-get install libatlas-base-dev

注意：执行sudo -H python3.7 -m pip install numpy==10.14.0 会出错。

请告诉在这种情况下还有什么可以帮助的？
