I installed psycopg2 following this answer but when I compile this code
import psycopg2
import pprint
import sys`
I get this error:
c:\code_python\tutorial>python main.py
Traceback (most recent call last):
File "main.py", line 16, in <module>
import psycopg2
File "C:\Python27.10\lib\psycopg2\__init__.py", line 50, in <module>
from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: DLL load failed: %1 no es una aplicaci¾n Win32 vßlida.
What is the problem with psycopg2?
Sorry for my question, the problem is i try install psycopg2 x86, when i install python x64 for my computer. I download psycopg2 x64 and all fine

I have a simple python program which I am running on a Mac machine.
import numpy as np
def main():
print("np arr test")
arr = np.array([1.0, 2.0, 3.0])
print(arr)
if __name__ == "__main__":
main()
I've verified that the numpy library was correct installed through pip
pip3 list | grep numpy
msgpack-numpy 0.4.4.3
numpy 1.16.2
numpydoc 0.8.0
I get the following error when I run the program

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.6 from "/usr/local/bin/python3.6"
* The NumPy version is: "1.18.4"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'
Process finished with exit code 1
Can you please help me figure out what I am missing? Appreciate your response!
NOTE : Based on the stack overflow post I updated the numpy through the following command
pip3 install numpy --upgrade
pip3 list | grep numpy
msgpack-numpy 0.4.4.3
numpy 1.21.2
numpydoc 0.8.0
WARNING: You are using pip version 21.2.1; however, version 21.2.4 is available.
However I still see the error message
Try to uninstall numpy and install it again.
I cannot import any python package when running python on Visual Studio code or on my Terminal. I can still do this if I were to code on a Jupyter notebook. However, when I tried other environment that doesn't use the notebook server. It returns me ModuleNotFound Error like this

Most of my packages was download via anaconda. I don't know if it might be the cause of this.
if I'm running
import urllib3
the following error occurs:

from socket import error as SocketError, timeout as SocketTimeout
ImportError: cannot import name 'error'
Please note that I replace < with > ahead of each >module> so the text in-between is still visible
Reinstalling python, pycharm and the libraries hasn't made any difference.
Many thanks for your help

My python version is 3.6. my OS is windows. After install rpy2 module, when I type import rpy2, got no issue. But when type import rpy2.ipython, got error as below:
>>> import rpy2.ipython
Warning (from warnings module):
File "D:\Soft_app\Python\lib\site-packages\rpy2\ipython\rmagic.py", line 76
"either.")))
UserWarning: The Python package 'pandas' is strongly recommended when using `rpy2.ipython`. Unfortunately it could not be loaded, and we did not manage to load 'numpy' either.

Can help to figure out what's issue??
It seems that you are missing Ipython and pandas. Installing them should resolve your issue.
Run "pip install ipython" to install Ipython and run "pip install pandas" to install pandas.
Hopefully, this will solve your problem.
Happy Coding ~
I use windows 7 and installed python 3.5 32bit. I installed numpy 1.11 + mkl win32 whl version for python 3.5 from http://www.lfd.uci.edu/~gohlke/pythonlibs/
and installed scipy 0.17.0 from the same site same way. I use pip install. No problem import numpy and scipy, but see error when import scipy.stats or from scipy import stats, etc... Here is the error message:

I have searched for solution from websites but could not find an answer. Please help. This is really frustrating...
Thanks

Ok, finally I solved this myself. At the beginning I knew I needed the 2015 visual C++ redistribution and had it installed, the problem is I installed the 64bit one while obviously I should have used 32 bit one since my python and numpy, scipy were all 32 bit.
Hope this helps for other people
