I have been trying to install numpy for Python 2.7.12 on a ubuntu 16.04 machine, but am not sure I am doing the right thing.
I issued the command
python setup.py install
and received the following error message:
ImportError: No module named Cython.Compiler.Main
So I have also been trying to install the cython package and received another error message:
/Cython-0.28.1/Cython/Plex/Scanners.c:19:20: fatal error: Python.h: No such file or directory
I thought this problem required me to install cpython. Trying to install this resulted in the following error message:
Traceback (most recent call last):
File "setup.py", line 4, in <module>
import sys, os, importlib.machinery, re, optparse
ImportError: No module named machinery
I am somewhat stumped about how to continue. Am I on the right path? Is there a different way I could try (the computer in question cannot connect to the internet)?
You can check if pip is install thanks to the command which pip,
in my case :
$ which pip
/home/usr1/anaconda3/bin/pip
If pip is not install install it : instruction here
then you should be able to use it such as :
pip install numpy
an alternative is to use : conda install
In the terminal use:
pip install numpy
If you get any error like 'permission denied', try:
sudo pip install numpy

I'm running arch and when I try to use aws in the terminal I get a python-like error:
Traceback (most recent call last):
File "/usr/bin/aws", line 19, in <module>
import awscli.clidriver
ModuleNotFoundError: No module named 'awscli'
This happened for pip as well which I resolved by python -m ensurepip but I don't know why it was like that in the first place. I even tried explicitly adding the path to aws to my PATH to no avail.
Well, pip and other applications are in fact python programs. Apparently you just lack the 'awscli' module. A first try would be just install this module.
Try this command
sudo pip install awscli --force-reinstall --upgrade
these are the Error messages I am geeting on running any of my project modules.

import cryptography
ModuleNotFoundError: No module named 'cryptography'
I have already installed the cryptography module and was working perfectly until today I start getting this message that " No module named 'cryptography'".
I have again installed the cryptography as well as pip package but still showing the same error.
There might be loose versions running on your system. Please try the following:
python -m pip uninstall cryptography
python -m pip install cryptography
You can also check out this with python -m to make sure you are not using a loose pip.
You might not have cryptogtaphy installed correctly. I see you are using windows. Open commandline as an administrator and run pip install cryptography again. Enshure that the installation finishes without any errors and consider to restart your python interpreter after installation.
For further help you should post more details like the output of pip and your code leading to the error, so a more detailed answer for your problem can be given.
Try download cryptography whl from here.
Then use pip install cryptography-XXX.whl
For example:
pip install cryptography-3.3.1-cp36-abi3-win_amd64.whl
And now just supports python2.7 and python3.6.
I am trying to create an image processing program using convolutions. I need the package scikit-image, specifically this:
from skimage.exposure import rescale_intensity
I have repeatedly installed scikit-image using pip install scikit-image in my terminal (Mac). I did this in the folder where my convolutions.py file is located (is this what is meant by the PYTHONPATH?). However, I always get an error message:
Traceback (most recent call last):
File "Convolutions.py", line 6, in <module>
from skimage.exposure import rescale_intensity
ImportError: No module named skimage.exposure
How do I solve the problem?
make sure you are installing the package on the same version of python which you are running. On a mac, python by default runs python-2.7, and the command python3 runs python-3.x. Also, pip by default installs packages to python-2.7. To install them on python3 try running
python3 -m pip install scikit-image
or simply
pip3 install scikit-image
I am trying to install Pytorch via pip on ubuntu 18.04.I have python 3.6 and my laptop is HP-Pavilion notebook 15
The installation seems to be right because i get the message:
Installing collected packages: torch, torchvision Successfully
installed torch-1.3.1+cpu torchvision-0.4.2+cpu
i run the verification code and it is ok
from __future__ import print_function
import torch
x = torch.rand(5, 3)
print(x)
However, when i close the terminal or reboot and try to run he same code i get the error:
Traceback (most recent call last):
File "torch.py", line 2, in
import torch
AttributeError: module 'torch' has no attribute 'rand'
How are you executing the python script? Which python are you using? Maybe you installed the package in a different python version?
Try to set alias to the python you want to use:
alias python=/usr/local/bin/python3.6
Then pip install the package with that python alias you will always be using.
python pip install <package name>
Python now will install the package in the python files with the alias python - heading to files: /usr/local/bin/python3.6
Let me know if the error still occurs!
Install pytorch using pip through the below command:
pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html
for any reference go through the official website of pytorch.
Change your file .py to another name, you named torch.py when you import torch it will call ur torch.py
I am on Mac OS Sierra, with home-brew, pip and python3 installed. I Tried running a script that required the requests module, but I keep getting this error:
Traceback (most recent call last):
File "listing_seq.py", line 1, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
Despite running:
sudo pip3 install requests
sudo pip install requests
sudo pip install requests --upgrade
Any suggestions?
Update:
When I try running using virtualenv I get:
Running virtualenv with interpreter /usr/local/bin/python3
ERROR: File already exists and is not a directory.
Please provide a different path or delete the file.
The most common error is having another file with the name of any of the libraries you requested in the same path.
The other possible error is if the python you are using to execute the file is not python 3 but rather the defalut python from your OSX. See the accepted answer on this for better understanding of a possible issue. Also share your code to identify the bug.
