I cannot seem to properly install pytorch on my computer, so here is the background of what I have done:
I had already installed python on my computer and it worked. I used it in Eclipse, using pyDev, so I don't know if that could be the problem. Now I want to install pytorch, so I installed anaconda and entered the command for installing pytorch. To get the right command, I use https://pytorch.org/get-started/locally/, where I tried the options both with and without cuda. In both cases I get an error when I type "import torch".
I have also installed miniconda and tried the same with that without succes. I also tried to work in IDLE in stead of Eclipse, but I keep getting the "no module named 'torch'" error. Each time I run a command in anaconda it appears that the installation is succesfull, but I still can't import 'torch'.
Any idea what the problem could be or what I could try?
Open command prompt or terminal and type:
pip3 install pytorch
If it says pip isn't installed then type: python -m pip install -U pip
Then retry importing Pytorch module
Using anaconda, I think you can check to see if pytorch is properly installed inside your conda environment using conda list inside your environment. If it is shown in the list of installed packages, you can directly try to run python in command line and import torch as in the official Pytorch tutorial:
import pytorch
torch.cuda.is_available()
For IDEs like Eclipse, you need to edit the settings of your project so that it uses the correct conda environment.
Try to create conda-env and reinstall pytorch on conda-env.
Then try to import torch again.
import torch
torch.cuda.is_available()
my python version is 3.7.5.
In vscode, I created my virtual environment
python -m venv myProj
Then I switch my python interpreter to: python3.7.5 64bit ('myProj':venv)
I install tensorflow as below:
pip install tensorflow
I can see tensorflow appear in the myProj/lib-sitePackages
Then I tried to run python file in which there is one line 'import tensorflow'
The prompt became like below:
(myProj) C:\Users\xxx\Documents\My_Document\myname\myProj>
I got error like below:
ImportError: DLL load failed: The specified module could not be found.
Failed to load the native TensorFlow runtime.........
Interestingly, when I did pip install tensorflow outside of virtual environment, I was able to run python3.7.5 and import tensorflow.
I spend hours try this and that. But got no success.
Do anyone know why it happens?
Run tensorflow in anaconda.
Delete and unistall all existing python software and download anaconda.then view tutorials of how to install tensorflow and keras in anaconda. It takes about 20 mins with goodnet speed.
I used to get the same dll error load module not found error when tried without anaconda.these are compatibility issues
Importing the numpy c-extensions failed
I installed python 3.7 on my windows system to work on visual studio code. Everything was going well, including using the libraries.
I uninstalled python using the uninstalling program tool in control panel. And installed Miniconda 3.
I checked that everything works well, and then installed the numpy library using conda install numpy in my terminal GitBash on windows 10, then checked it on my visial studio code, but it failed to start.
Reproducing code example:
import numpy as np
A = np.array([[-1], [7], [-26]])
Error message:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "C:\Users\ramim\Miniconda3\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.17.3" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
If you're working with a numpy git repository, try git clean -xdf (removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: DLL load failed: Не найден указанный модуль.
Numpy/Python version information:
Python 3.7.5
Numpy 1.17.3
I tried to uninstall and install the numpy library again, but it was useless.
Note: when I type in the teminal conda install numpy, it says:
All requested packages already installed
That's how I checked if numpy is really installed!
How to solve that?
Try to uninstall numpy and setuptools first:
pip uninstall -y numpy
pip uninstall -y setuptools
pip install setuptools
pip install numpy
Borrowed from solution provided by mehdiHadji here- https://github.com/ipython/ipyparallel/issues/349
Not sure this is a thing in Visual Studio too, but for Eclipse I had to change one of the environmental variables.
Setup: Windows, Python 3.7, Conda venv with numpy
Solution:
CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1
For Eclipse, the environment variables can be accessed via Properties -> Run/Debug Settings -> Edit -> Environment.
Anaconda also documented the fix, albeit for a different problem:
Conda Troubleshooting
Similar with my problem recently. I'm using Python 3.8 by Miniconda on Win 10 system. I solved the problem by changing default terminal from PowerShell to Command Prompt.
Steps:
Open VS Code's Command Palette menu by pressing Ctrl+Shift+P or F1
Choose "Terminal: Select Default Profile" entry
Then pick "Command Prompt" option
Restart VS Code
This issue is caused by VScode default terminal (powershell) setting,
To switch VScode default terminal from powershell to cmd, the conda env will be activated correctly, other powershell will try to invoke conda activate xxxxxx which will fail, then the subsequent import numpy will fail.
So two ways to fix it:
Fix path search issue under powershell environment to get conda activate xxxxxx successfully executed;
Change vs code default terminal to 'cmd':
add "terminal.integrated.shell.windows": "C:\Windows\System32\cmd.exe" in settings.json
I solved this by the following steps-
Uninstalling numpy and pandas with conda
Installing numpy and pandas with pip
I solved the problem by reinstalling NumPy through pip:
pip install --upgrade --force-reinstall numpy
I solved it by removing ALL numpy versions
pip uninstall numpy
pip3 uninstall numpy
And then installing numpy and libatlas-base-dev via apt-get
sudo apt-get remove python3-numpy
sudo apt-get install libatlas-base-dev
It looks like there's something wrong with your %PATH%. It might either contain some conflicts, or just be too long (>2047 chars). Try adding the folder with the dlls (from the environment you're trying to use) to the very beginning of it:
PATH=C:\Users\ramim\Miniconda3\Library\bin;%PATH%
python -c "import numpy"
(based on this)
For those scratching their head wondering why re-installing numpy module works:
If you are using a virtual environment (say in a relative location called env), make sure that folder does not make it to other platforms like Docker, or different OS you might be switching to.
Remember the compilation of Python and C extensions necessary for numpy are platform dependent. So if it works in Windows, it will not work in Linux using the same virtual environment (cached modules).
For example, this is particularly important if you are running your code on Windows - and then try to run it on a Linux container via Docker Desktop. (Make sure env - or whatever your virtual env is called - is ignored and not copied onto the container)
I had the same problem, and tried several of the solutions given here, but none worked for me. I looked in another forum and was able to solve the problem (https://github.com/numpy/numpy/issues/13252):
conda uninstall numpy
pip3 install numpy.
This issue is still ongoing. I use VS code with conda venv, and solved it in a similar way with marineCoder:
In addition to numpy and pandas, I also remove matplotlib using conda uninstall
Cautiously reinstall pandas and numpy using pip install
In my case, the error shows up whenever matplotlib package is installed, so I got to either remove it or downgrade the three of them. There is a clash on numpy dependency. Another related issue is shown in this post:
I get `No module named _multiarray_umath` when using matplotlib
In my case, I had to manually 'conda activate myenv' the desired environment in the VS code terminal. Previously, I only had to select the python version from the desired environment, and then the environment would auto-activate. This answer references and confirms Brett Cannon's comment above, which was the sole reason I thought to try it.
As I'm on MacOS (with an M1 CPU) I realize my answer is not exactly an answer to the poster's question but as I got the same error and Google sent me here perhaps this helps someone.
In my case I found the error was caused because VSCode was still running in Intel-X86 mode on my Mac-M1. Simply re-installing VSCode using the latest "Mac Universal" distribution switched it to ARM64 mode fixing the issue for me.
Uninstalled anaconda and installed latest version
I tried the answers here but they didn't work for me, uninstalled older version of anaconda (don't remember previous version number now) and installed Anaconda3-2022.05 (Anaconda Navigator 2.1.4). This sorted it for me. I hadn't used my anaconda setup in long time and thus didn't care if my preinstalled packages get wiped out. This took a lot less time and saved from pain of trying more approaches.
OS: Windows 10
Please check both of these (your PATH or PYTHONPATH environment variables) carefully to see if they are what you expect.
In my case, there was an issue related to updated versions of python and NumPy, I resolved both problems by running a single command over conda PowerShell prompt i.e. conda update --all
Here are the steps-
Open Anaconda Powershell Prompt and click 'run as Administrator'.
Enter the following code into the prompt and click enter: conda update --all ...
You are all set to run your script
I hit this error while running a block of code in a .ipynb Jupyter Notebook file.
I fixed the problem by switching the version of Python that was running. Specifically, I was running Python 3.8.5 from the Anaconda3 directory on my computer and I switched this to Python 3.9.2 that I had installed elsewhere on my computer.
To toggle the version of Python in VSCode while working on a .ipynb file, click on the version specified in the top-right corner of the screen. Thereafter, a dropdown menu will allow you to select from different versions of Python installed on your computer.
For my situation, I had updated the version of python that I was using. Running git clean -xdf resolved the issue.
My system:
OS: Mac OS 11.6
Python: 3.7.8 => 3.8.12
Numpy: 1.20.2
Poetry: 1.1.6
I'm totally new using Python and I have to learn quickly because of my job. I have downloaded Python2.7.13 (and also the pip package. My next step was:
C:\Python27\pip install keras
And it finished saying that theano and anaconda2 were installed to and also was fine.
The problem came when I tried the following line:
C:\Python27\python
>>>from keras.models import Sequential
And I get the following message (after others that don't give error):
ImportError: No module named numpy
The fact is that I got out of python and try pip install numpy and it says that I have already have numpy installed and show me in which folder I have it. So I go to that folder and try:
C:\users\maca\anaconda2\lib\site-packages\numpy\python setup.py install
And that returns:
This is the wrong setup.py file to run
I'm totally new so I'm very lost about what my next step should be and how to fix it, 'cause I'm not familiarized with Python. I would thank any understandable help.
Thanks in advance.
It sounds like you have vanilla python installed in C:\Python27\ and Anaconda installed in C:\Users\Maca\Anaconda2. These are different. Anaconda is not an add-on to python, it is a distribution of python. Anaconda will have the math prerequisites, vanilla will not. You can install Keras on vanilla (it's hard), but it sounds like you want to use Anaconda. Then use only anaconda. Run:
activate root
You should then be using Anaconda and you can run:
pip install keras
Also, keras works on top of a backend so make sure you either have theano (pip install theano) or tensorflow.
Then, in the same console window, using Anaconda, run python and type from keras.models import Sequential. It should work.
From then on, you can access anaconda (as long as it was set up with this command enabled) with activate root. This will set python and related arguments to refer to Anaconda rather than the default C:\Python27.
EDIT: If in the future you are planning to use only anaconda, you can delete C:\Python27 from your path or even add Anaconda to it. To add anaconda to you path, look up environment variables in the start menu, go to the system environment variables, and find PATH. If you haven't uninstalled Python27 yet you'll need to remove C:\Python27\ from that path, and then you can add C:\Users\Maca\Anaconda2 anywhere (probably towards the end depending on how often you use python and how cluttered your path is).
You are already using Anaconda Python distribution so you should use conda package manager for installing keras: run conda install keras in your terminal. This will install keras and all the dependencies.
I want to use "pyomo" for my studies. I installed pyomo via easy_install
coopr install instructions, Pyomo needs a solver to work so I wanted to install the
(GNU Linear Programming Kit) glpk_webpage, pyomo seems to be installed just right because I can import it in spyder (i am using WinPython-64bit-2.7.5.3) with
import coopr.pyomo
However, I cannot do anything without glpk I guess...
I downloaded glpk-4.52 (latest version) from the ftp server but I do not know what to do with the batch files I found in the "w64"-folder I should use(?) according to "Installing GLPK"
I do not have Visual Studio installed - Isn't it possible to work without it?
I recently installed GLPK for use with python 3.5 and pyomo under windows 7 and would like to report how I succeeded. I installed pyomo via:
pip install pyomo
Then, download WinGLPK 4.55 from here: WinGLPK
This does not work for newer versions at the moment.
Unzip it and copy the whole w64 folder to C:\w64
Include folder C:\w64 in your system PATH (so that glpsol.exe is found).
Check your installation using the simple example from the official pyomo documentation:
pyomo solve abstract1.py abstract1.dat --solver=glpk
The files abstract1.py and abstract1.dat can also be found in the pyomo documentation.
I hope this will help the next desperate GLPK installer.
FYI, you can now use Coopr without installing local solvers. The latest Coopr release supports an interface with the NEOS solver. For example, if your MILP model is in the file model.py, then the following command would optimize the model using CBC:
pyomo --solver-manager=neos --solver=cbc model.py
Better late than never: in order to use GLPK (executable glpsol.exe), it must be somewhere on your sytem environment variable "Path". For sake of an example, let's assume you put the GLPK executable into the folder C:\GLPK\bin. Then (steps copied from this answer by melhosseiny):
Hold Win and press Pause.
Click Advanced System Settings.
Click Environment Variables.
Append ;C:\GLPK\binto the Path variable.
Restart command prompt.
Now try to launch glpsol from any directory. If it is found, pyomo should now be able to use it.
If you are using Anaconda, both pyomo and glpk can be installed with conda install. In the Windows terminal, activate your conda environment, then:
conda install -c conda-forge pyomo
conda install -c conda-forge glpk
To test the glpk installation:
glpsol --help
