ModuleNotFoundError: No module named 'torch'

[xiaonengmiao]

• OS: macOS High Sierra version 10.13.2
• PyTorch version:
• How you installed PyTorch (conda, pip, source): pip3
• Python version: Python 3.6.0 :: Anaconda 4.3.0 (x86_64)
• CUDA/cuDNN version: No GPU

I successfully installed torch and torchvision using pip3 but
when type "import torch" in jupyter notebook i get the following

ModuleNotFoundError Traceback (most recent call last)
in ()
----> 1 import torch

ModuleNotFoundError: No module named 'torch'

import sys
print(sys.executable)
/Users/user/anaconda3/bin/python

[vishwakftw]

Since you have conda, could you try installing using conda?

[xiaonengmiao]

@vishwakftw conda install pytorch torchvision -c pytorch
and got this
PackageNotFoundError: Package not found: '' Dependencies missing in current osx-64 channels:

• pytorch -> mkl >=2018
• torchvision -> pytorch >=0.3 -> mkl >=2018

[xiaonengmiao]

@vishwakftw for PackageNotFoundError I tried this:
$conda update conda
$conda install mkl=2018
which I found here
and it works now
Thanks vishwakftw

[Jerrybonheur]

I've the same error"ModuleNotFoundError: No module named 'torch'" when debugging my code.
How to handle it?
Thanks

[xiaonengmiao]

@Jerrybonheur
If you have conda, try installing pytorch using conda (on mac for example):

$conda install pytorch torchvision -c pytorch

If this still dose not work, then try:

$conda update conda
$conda install mkl=2018

[nicospbr]

I have tried the three steps given by @xiaonengmiao, still "ModuleNotFoundError: No module named 'pytorch'"

Any ideas?

[jithinjk]

Faced similar issue in Windows 10 with Anaconda installed. Installed pytorch package using conda install command which I found here: http://pytorch.org/

The usual import from command-line worked for my environment(torch):

(torch) C:\Users\torch>python
Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 10:22:32) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
>>>  

But, when I tried to import this package from Jupyter notebook, I got following error message:

ModuleNotFoundError: No module named 'torch'

Then, I tried installing Jupyter notebook application from Anaconda navigator for my environment(torch).
Restarted my Jupyter notebook and ran import torch and this time it worked.

[ghost]

@nicospbr If it's still not resolved, run conda list and check whether jupyter is installed or not. If not, run conda install jupyter . Now, open jupyter notebook and run import torch .

[YakshThakar]

pip3 install http://download.pytorch.org/whl/cpu/torch-0.4.0-cp36-cp36m-win_amd64.whl
do this for windows 10 its work fine @xiaonengmiao

[romanovacca]

For me installing these steps made it work:

1- installing -> conda install nb_conda
2 - installing -> conda update conda
3- installing conda install mkl=2018

[atan4583]

This is what I found :

If you have more than one environment in Anaconda, jupyter, pytorch and torchvision need to be installed in the same environment. Otherwise, jupyter won't find the other 2 from where it is launched. Unless you know how to 'make jupyter aware' of the path to the environment where the other 2 reside, the fix is to have all 3 in the same environment.

[jleni]

@atan4583
Yes, oddly enough.. I had the following situation:

from a new console

• create conda environment 'conda create -n test'
• installed torch
• run 'import torch' works

from a jupyter console

• switch to the same environment 'source activate test'
• conda list -> torch is already there (and just tested)
• run 'import torch' in the jupyter console window fails

[soumith]

the Jupyter package must be installed in the base environment and not in this new environment. From inside a Jupyter console, if you do switch to the same environment 'source activate test', that does not update the Jupyter's PYTHONPATH at all.

[jleni]

True, but I tried to import in the same jupyter-lab console where I switched to the other environment. That is why it is odd.

[jleni]

mm.. It seems that I hit this issue here: jupyterlab/jupyterlab#4672

import torch it is working well with jupyter notebook but it fails with jupyter-lab

[imflash217]

@jleni , I'm also facing the same issues. import torch works fine with jupyter-notebook but not with jupyter-lab if I'm connecting to a remote server. But if I'm connecting to my local machine, then both work fine.

[erseler]

I have removed all the packages related to torch, then reinstalled. It worked for me since the conda mixed up the versions of the torch packages.

List torch related packages:
conda list | grep torch
Remove and reinstall the packages:
conda uninstall torchvision-cpu pytorch-cpu
conda install pytorch-cpu torchvision-cpu -c pytorch

[ervin-x]

The command to import pytorch is:

import torch
not
import pytorch

[JimLiu0327]

      The command to import pytorch is:

import torch
not
import pytorch

i am facing the first question. and any help will be thinks.

[caothuong]

I installed follow link: https://pytorch.org/. It works for me

[lal1234]

pip3 install http://download.pytorch.org/whl/cpu/torch-0.4.0-cp36-cp36m-win_amd64.whl
do this for windows 10 its work fine @xiaonengmiao

it will not work..it successfully installed torch but while running command import torch it showing module not found error

Have you figured out this issue? I guess i met the same problem as yours

[MxGutierrez]

same problem here. I installed pytorch but when i try to run it on any ide or text editor i get the "no module named torch". However, it does work in jupyter notebook and ipython (from cmd). Any possible solution?

[lamnguyenx]

I'm having the same issue.

It's slightly different in my case, since I was installing pytorch with anaconda without internet connection. Here's my script:

CONDA_PACKS="/path/to/conda_packages"
conda install --offline --verbose ${CONDA_PACKS}/ninja-1.8.2-h1ad3211_1001.tar.bz2
conda install --offline --verbose ${CONDA_PACKS}/resampy-0.2.1-py_1.tar.bz2
conda install --offline --verbose ${CONDA_PACKS}/pytorch-1.0.1-py3.7_cuda90_cudnn7_1.tar.bz2

Any ideas?

You need to configure the environment path for the anaconda python, then I think you can run in IDE. But I haven't found how to fun in command prompt yet.

[lamnguyenx]

Turns out that was version mismatch of installed plugins.

I used "conda install" command provided on the plugin page to check the exact version strings of the dependencies and then downloaded them one by one.

If you want to install pytorch inside a conda environment, please use pip instead of pip3.

[saraXX]

all solution above didn't work :(

[urayoru113]

I think the problem is that jupyter is the global jupyter, not the jupyter in local environment.
So I try:
$activate (my env)
$(my env) pip install jupyter
and then
$(my env) jupyter notebook
It worked for me

[sreshu]

"import torch" not working in jupyter notebook

OS: Ubuntu 18.04
Python version : 3.6.9

[obbrc]

I had the same problem in conda. I have tried all solutions, none seem to be working. I have noticed that I had activated my pytorch environment from another conda environment. When I deactivate my pytorch, it goes back to second environment, not base. When I deactivated all, and re-activated pytorch it worked fine.

[kanhataak]

First you should have separate environment in Anaconda

conda install pytorch torchvision cpuonly -c pytorch

after run this installing getting error ModuleNotFoundError: No module named 'torch'

in the case of you need to install "conda install jupyter" after install notebook

import torch
not pytorch

[DebadityaShome]

In a system with multiple conda environments you need to install jupyter and torch again in that particular environment, otherwise conda can't import packages from other environments.

[bakaito]

@nicospbr If it's still not resolved, run conda list and check whether jupyter is installed or not. If not, run conda install jupyter . Now, open jupyter notebook and run import torch .

I have jupyter installed in conda but still can't import torch

[fathia-ghribi]

when i run import torch , an error occurs ModuleNotFoundError: No module named 'torch'.

[DebadityaShome]

@fathia-ghribi Can you give more details which OS / Environments are you using?

[bakaito]

If it's a jupyter notebook and you have installed pytorch in a different environment than the default one, make sure you activate the one where pytorch is installed (conda activate <env_name>)

[fathia-ghribi]

i tried with (https://pytorch.org/get-started/locally/)
but

[fathia-ghribi]

hi all,
no one can help me to solve this error.

[hjw21century]

First, you should get which jupyter you are using by 'which jupyter' command.
Then, you get which python interpreter you are using by 'vim /usr/bin/jupyter' for example.
If the python version is not what you expected. now reinstall jupyter binded with the python version you expect.

[hjw21century]

Also, you can directly check the jupyter kernel setup in '/usr/local/share/jupyter/kernels/python3/kernel.json' file.

[priyarana]

all solution above didn't work :(

Nothing is working for me. Did u solve the problem finally? thanks

[ankitajaiswal00]

I had the same problem where the jupyter lab couldn't import torch after successful installation in my virtual environment. But when I checked the list of installed packages using 'conda list', PyTorch was present but not jupyterlab. After installing jupyterlab, it is working fine!.

[Anhar2]

Installing pytorch in the base and using the base kernel "i.e Python3" in jupyter notebook only worked fine, using any other kernel with pytorch installed never worked

[bralat]

I use WSL and what worked for me was installing mkl=2018 as suggested in previous answers,

conda install mkl=2018

then closing my windows terminal and reopening it.

[jaydeepsb]

Solved!
I had similar problem. I created conda env called torch.
Within command line ipython, I could import torch successfully. But when I tried to import torch inside jupyter notebook it failed.
The problem was due to the way I registered my new env kernel called torch. I was in a different (wrong) env when I ran the following command.
python -m install ipykernel --user --name=torch --display_name='torch

This I realized by printing import sys; sys.path in jupyter notebook. It was pointing to different site-packages folder.

Correct solution is -

conda activate your_torch_env
conda install ipykernel #if you have not installed already
ipython kernel install --user --name=your_torch_env

[AnjaniSonavane]

conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch

[YUyttendaele]

What worked for me was reinstalling jupyter notebook:

conda install jupyter notebook

[w3nhao]

$ conda activate your_torch_env  
$ conda install ipykernel #if you have not installed already  
$ ipython kernel install --user --name=your_torch_env  

Try this first, if it doesn't work, you can add the path of your env' python manually to the kernelspec json file.

Find your env' python' path by:

$ whereis python

Copy the path and manually put it into the kernelspec newly generated:

$ vim /home/your_user_name/.local/share/jupyter/kernels/your_torch_env/kernel.json

[jiwan-swfit]

@Jerrybonheur conda가 있는 경우 conda를 사용하여 pytorch를 설치해 보십시오(예: Mac).

$conda 설치 pytorch torchvision -c pytorch

이것이 여전히 작동하지 않으면 다음을 시도하십시오.

$conda 업데이트 conda $conda 설치 mkl=2018

감사합니다. 해결 됬어요
