“RuntimeError:implement_array_函数方法已具有docstring”，正在尝试导入numpy。我如何解决这个问题？

Question

我正在尝试运行导入numpy的脚本，它显示以下错误：

Traceback (most recent call last):
  File "C:/Users/knaraghi/pycharm/ai_ems/ems-gym/examples/rllib_example_IKDG_system.py", line 5, in <module>
    import numpy as np
  File "C:\Users\knaraghi\pycharm\ai_ems\ems-gym\venv_ems-gym\lib\site-packages\numpy\__init__.py", line 142, in <module>
    from . import core
  File "C:\Users\knaraghi\pycharm\ai_ems\ems-gym\venv_ems-gym\lib\site-packages\numpy\core\__init__.py", line 24, in <module>
    from . import multiarray
  File "C:\Users\knaraghi\pycharm\ai_ems\ems-gym\venv_ems-gym\lib\site-packages\numpy\core\multiarray.py", line 14, in <module>
    from . import overrides
  File "C:\Users\knaraghi\pycharm\ai_ems\ems-gym\venv_ems-gym\lib\site-packages\numpy\core\overrides.py", line 47, in <module>
    """)
RuntimeError: implement_array_function method already has a docstring

Process finished with exit code 1

我用谷歌搜索了一下，结果是

1. 这可能与多次导入numpy有关
2. 它可能与python可能运行的一个名为usgwi的软件有关

我使用的是python 3.7和numpy 1.18.5

谢谢大家!

Answer 1

我认为这是努比的问题。 见https://github.com/numpy/numpy/issues/14384

我在使用python AREPEL的VSCode中遇到了问题。我修正了：

python3 -m pip install user numpy -U

$ python3 -m pip freeze | grep numpy
numpy==1.19.4
$ python3  version
Python 3.8.6

Answer 2

将numpy降级为numpy==1.15.4将解决此问题

pip install  no-cache-dir -I numpy==1.15.4
