I have just downloaded PyTorch with CUDA via Anaconda and when I type into the Anaconda terminal:
import torch
if torch.cuda.is_available():
print('it works')
then he outputs that; that means that it worked and it works with PyTorch.
But when I go to my IDE (PyCharm and IntelliJ) and write the same code, it doesn't output anything.
Could someone please explain to me how I can somehow get this to work in the IDE?
It was driving me mad as well... What finally helped me was the first link that says to use PyCharm "Terminal" to run the pip install command (from the PyTorch website). That fixed all my problems. (I had installed pytorch 3 times by that time and tried different interpreters...)
https://www.datasciencelearner.com/how-to-install-pytorch-in-pycharm/
pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio===0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
I hope this helps save someone hours of headache. :)
I also spent over 10 hours trying to figure out what was wrong. I ended up checking if there is something wrong with interpreter.
What was the problem is version of python (I had v. 3.8). After upgrading to newest version, problem was solved.
Check your version using command:
python --version
If your version is old (current is 3.9.2), install newest one from official python site:
https://www.python.org/downloads/release/python-392/
After installation make sure you using newer version (use command above)
I had a similar issue.
Inspired by #the-lay answer, calling import os; os.system('') resolved my issue.
Another possible root of the problem is running a Flatpak version of Pycharm. Took me some time to figure out, but Flatpak does not load user specific environment variables files (i.e. ~/.profile, ~/.bash_profile and conda environment). I have deleted Flatpak version and installed a snap version (sudo snap install [pycharm-professional|pycharm-community] --classic) and it loads the proper PATH which allows loading CUDA correctly.

I got error message when I am trying to setup tensorflow.
I examine a lot of discussion from github issues. I tried different versions but output doesn't change.
I saw this previous question in stackoverflow too but there is no answer avaliable.
I am trying to be more specific about error and platforms I am currently using and I hope someone help me or show me different approaches.
First of all I had python 3.6.x
but I deleted this version cause I want to make this setup clearly.
I downloaded Anaconda (Anaconda Python 3.7 version)
After that I checked my python version and its changed like 3.7 as I expected.
After that I follow the guide for setup tensorflow
conda create -n tf-gpu tensorflow-gpu
Because I want to use my gpu which is much faster comparing with CPU
(I already checked my gpu compability for tensorflow,I am currently using rtx 2060)
Summary:
-Anaconda Python 3.7 version
-Python 3.7.4
I solved my problem about insalling tensorflow maybe it will help other people.
Firstly, I just cleared my PATH under the Environment Variable which are related with Anaconda or you can delete Anaconda and reinstall.
After that open Anaconda command line and write:
pip install tensorflow-gpu
Edit: You might want to skip to the end of the question first, I've followed some advice in comments / answers and the current error is different from the original (appears to be related to numpy possibly).
This error ModuleNotFoundError: No module named 'torch' shows up in tons of threads, I've been trying solutions all day. I'll go through my troubleshooting steps one by one, using the solutions suggested in threads.
System info:
Windows 10
First thing I did was follow the instructions on Pytorch, installed Anaconda and did this using the correct settings for my machine (Note: I tried Python v3.7 before trying v3.8 in these screenshots, none of the solutions worked with that either):
As you can see, that should be good to go, according to the instructions.
So I go into the python terminal and try to import pytorch, like so:
ModuleNotFoundError: No module named 'torch' Great, so what now? Well I paste the error into Google and begin my 4 hour wild goose chase.
First result, stack overflow answer: No module named "Torch"
Let's try the selected answer, it requires some version-related syntax so lets check my python version:
Alright so as directed by the answer:
Try to install PyTorch using pip:
First create a conda environment using:
conda create -n env_pytorch python=3.6
Ok:
Activate the environment using:
source activate env_pytorch
That doesnt work, but if we activate using the instructions given by the prompt, we can do so:
Now install PyTorch using pip:
pip install torchvision --user ( this will install both torch and torchvision)
Hmmm.. well that went up in flames, so the following...
Now go to python shell and import using the command:
import torch
import torchvision
...doesn't do anything new, same error as before.
Well, to the next thread, on PyTorch GitHub: https://github.com/pytorch/pytorch/issues/4827
They're trying to use Jupyter, so I tried this, is was another long process like the above that went up in flames, and I really dont want to need to use Jupyter anyway, so we'll skip this one.
Another Pytorch GitHub thread: https://github.com/pytorch/pytorch/issues/12004
#edtky Could you please give me the output of the following commands
in CMD?
where conda.exe
where pip.exe
where python.exe
Sure I'll give it a shot:
#edtky Looks like you have two Python environments. Please try
importing torch in Anaconda Prompt.
Oh well, I already did that. No bueno.
Another thread: https://discuss.pytorch.org/t/modulenotfounderror-no-module-named-torch/7309 suggests:
In that case you’ve probably forgotten to activate the environment
where pytorch is installed. It can also be the library missing in your
PYTHONPATH variable.
Well I did activate the environment as shown above, but I dont know anything about a PYTHONPTH variable, seems like the PyTorch setup guide wouldve mentioned if I needed to manually do that, I have no clue how to do it and you aren't explaining, so lets look for other answers.
Someone made a whole article to give us this little gym of advice: https://medium.com/#valeryyakovlev/anaconda-no-module-named-torch-ead10946de66
Another beginner error I encountered when started to use pytorch in
anaconda environment
import torch ModuleNotFoundError: No module named ‘torch’ the proper way to install pytorch to anaconda is following
conda install -c pytorch pytorch It’s not enough to simply run “conda install pytorch” — the package won’t be found. So first
activate your conda profile with “source activate {your_profile}” and
then run the command conda install -c...
Ok thats new info, let's try that command again now that our env is activated:
Ok that's a lot of green, let's try now...
Well we can't win 'em all, so lets go onto the next thread: https://forums.fast.ai/t/modulenotfounderror-no-module-named-torch-windows-10/12438/2
I had also faced the similar problem , I just installed torch and torchvision using pip and it worked …
Ok! Let's try:
Oh well, another solution up in flames..
I ran into a similar issue with Windows 10. In the end I could only get torch installed with Miniconda.
Alrighty, lets try it!
Alright, cool, moment of truth:
Awesome! You just read through 25 minutes of me re-producing all my attempts to solve this problem, and it doesnt even include the hour I spend down a rabbit hole trying to use Jupyter, which failed equally as miserably. I think it's time to post the question to StackOverflow!
Edit 1:
An answer points out that one of my logs was an error python 3.8 isn't compatible with pytorch, good point I'll fix that. After unintalling 3.8 and installing 3.7:
And no luck! Remember I actually mentioned in my first paragraph that while I was trying 3.8 in these screenshots, the first time around I did all of this with 3.7
Edit 2:
I forgot to install after activating the environment in the previous edit. Once I fixed that, there's a new error:
Pytorch requires 3.5 <= python < 3.8. Setup an environment with:
conda create -n pytorch python=3.7
conda activate pytorch
conda install pytorch
You should also make sure that you launch the installed python interpreter from this environment (YourAnacondaInstallDirectory\envs\pytorch\python.exe) from the activated conda environment! The later is important because conda will export certain environment variables (have a look at this for a related issue caused by missing envionment variables).
Use This Let me Know if it will Work!
pip install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp37-cp37m-win_amd64.whl
If you would like to install it with plain pip rather than conda:
As you know, Pytorch 1.5.1 requires 3.5 <= python < 3.8. Use Python 3.7 or slightly earlier.
Do NOT try to install with simple pip install torch. Instead, as you say, go to https://pytorch.org/, in the colorful grid, click on pip, copy the command, open a command prompt as an administrator (right-click and select "Run as Administrator") then paste the command, which should look something like:
pip install torch===1.5.1 torchvision===0.6.1 -f https://download.pytorch.org/whl/torch_stable.html
Then, edit the command to replace pip with the full path to your version of pip, e.g.:
"C:\Program Files\Python37\Scripts\pip.exe" pip install torch===1.5.1 torchvision===0.6.1 -f https://download.pytorch.org/whl/torch_stable.html
(You don't need to edit the command as long as Python 3.7 is in your path.)
I am installing python on windows10 and trying to install the opencv and numpy extentions in the command window. I get no error installing them and it says it is successfully installed. But when I try to check the installation and import cv2 it does not recognize it and give me the error: no module named cv2.
can anybody help me with this problem? Is there something wrong in installation process or do I need to install something else?
I checked the newest version of each and used the compatible one with my system.
Thanks.
One solution could be that you have 2 versions of python. So, go to the specific python's scripts directory and run: pip install numpy
If that too doesn't work, you can find the answers to this question on Why can't I import opencv3 even though the package is installed?, as stated by #Cut7er.
I have tried the solutions given to the above stated question myself also. But, they didn't work for me. So, another thing that you could try to use is this IDE called PyCharm. It ofcourse is much more beautiful that the IDLE, but it also has an inbuilt GUI controlled installation of binaries or packages. That would make things a lot easier. I have faced a lot of issues with packages for python and this IDE made things a lot easier. You can find it on https://www.jetbrains.com/pycharm/download/#section=windows.
You can also use anaconda. But, I found it a little difficult to use since, it has similar issues.
EDIT:
Seems like you are using PyCharm. But, you are installing libraries from your command prompt. So, see the answer to: ImportError: No module named 'bottle' - PyCharm. This answer guides you through how to install a certain library through your PyCharm window itself. So,
1) Go to Files>Settings
2) Search for "Interpreter" from the searching tab. Open the interpreter
3) You can now see a plus sign on the right. A click on it will open up a section on the left.
4) In the searching tab, search for numpy or opencv. Click on whichever module you want to install. And then click on the "install package" button on the bottom left. This will install the package for you.
5) Then click save. And run your file that says import cv/cv2.
This should probably do the trick.
Hope it helps!
Is it possible that you have 2 versions of python on your machine and your native pip is pointing to the other one? (e.g. you pip install opencv which installs opencv for python 2, but you are using python 3). If this is so, then use pip3 install opencv
I removed the Anaconda version on my machine, so I just have python 3.7 installed. I removed the python interpreter(Pycharm) and installed it again and the problem got fixed somehow!
I suspect you have two versions of python and the one you're using doesn't have opencv on it, because pip pointed to the wrong one.
A pragmatic solution assuming you're using the python version with conda is to just use conda to install cv2:
conda install -c menpo opencv
A more careful solution is to figure out how to get the pip that points to the python version you're using. On linux I can check that my pip points to my python like this:
:~$ which python
/home/kpierce/anaconda3/bin/python
:~$ which pip
/home/kpierce/anaconda3/bin/pip
So you see the pip and python versions are associated. On windows I suspect you do an analogous thing on the command line like
where python
where pip
And if they don't match, you might try
where python
where pip3
to see if those match. You need to use the pip that points to the correct python version. You can view the python version by entering the python interpreter and running
import sys
sys.version
I'm trying to update/upgrade my Python with conda. I run the command:
conda update conda
but it crashes my Python:
Python has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
My installation information is:
conda version : 4.5.2
conda-build version : 3.0.27
python version : 3.6.3.final.0
I googled the issue and got this github issue report. Unfortunately none of the solutions worked for me. I would appreciate if you could help me know what is the problem and how I can solve it.
I tried uninstalling and reinstalling conda and the problem disappeared temporarily. But then the issue happened again while I was trying to use matplotlib.
I experienced the exact same issue one a different machine when running conda update --all so either there is something wrong with conda or I'm making one mistake twice! (conda/python versions were exactly the same as above.)
I tried updating/upgrading all of the packages running the command in this post on admin-cmd. It took a long time to finish and the problem was still there.
There seemed to be issues with Qt. So I tried to uninstall and reinstall Qt and pyqt but it did not solve the problem either.
temporary workaround: I completely uninstalled Anaconda and installed stock Python. So far this has solved the problem both on my home and work computers.
Try conda update --all or if you're trying to update / upgrade specifically python then try conda update python. Faced such problem and it worked for me.
As was suggested by the mods, here I post my temporary solution. Considering that none of the other attempts (reinstalling Qt, Anaconda, updating with pip...) worked, I ended up uninstalling Anaconda and everything pythony and installed the stock / vanilla python from the official website. This has solved the issue so far. Please consider this is not a solution to the problem mentioned above but just to get the python working for the time being.
I'm struggling to understand why Pycharm is not recognizing OpenCV package installed via Conda.
Conda list command
Pycharm package list
I've noticed that a few times before as well but not as much lately. The first thing I would try is to upgrade to the latest version of PyCharm.
You may just want to peruse their forum if that doesn't help, but it sounds more like a bug to me.
