Vin*_*iLL 4 shell numpy python-3.x pandas google-cloud-platform
我最近开始使用 Google Cloud Platform,并在 Linux 环境中的 Cloud Shell 中运行 python 脚本。
通过运行使用 pandas 库的脚本之一,我遇到了非常令人不快的错误:
Traceback (most recent call last):
File "pandas_excercises.py", line 1, in <module>
import pandas as pd
File "/home/dann_frol/.local/lib64/python3.6/site-packages/pandas/__init__.py", line 17, in <module>
"Unable to import required dependencies:\n" + "\n".join(missing_dependencies)
ImportError: Unable to import required dependencies:

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
was
installed.

Please note and check the following:
* The Python version is: Python3.6 from "/usr/bin/python3"
* The NumPy version is: "1.19.0"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: /home/dann_frol/.local/lib64/python3.6/site-packages/numpy/core/_multiarray_umath.cpython-36m-x86_64-linux-gnu.so: failed to map segment from shared object

我检查了 python 和 numpy 版本,它们似乎与错误消息中描述的版本匹配。我尝试使用python3 -m pip uninstall pandasand重新安装 pandas 和 numpy python3 -m pip install pandas,但是没有帮助。
当我运行代码时,我使用以下命令:python3 pandas_excercises.py
有关操作系统的一些信息:
Operating System: Container-Optimized OS from Google
Kernel: Linux 4.19.114+
Architecture: x86-64

我非常确定,对于 Python 库的本机,该消息failed to map segment from shared object意味着该.so文件未标记为可执行。(ls -l说例如-rw-r--r--而不是-rwxr-xr-x。)
(我能想到的)在理智之后的唯一方法pip install是如果文件系统安装了noexec标志。(我的设置就是这种情况。)您可以使用mount命令快速检查它,如果设置了它,它将列在大括号内的其他标志中。
如何删除该noexec标志是另一个问题。
