Before we start we will discuss first if what is Pytorch.
What is a Pytorch?
Pytorch is a profound learning library which is
compatible with different
hardware configurations like
Central Processing Unit(CPU) and also the
GPUs. The installation procedure of
Pytorch is somewhat different for multiple hardware configurations.
Why the modulenotfounderror: no module named torch occur?
ModuleNotFoundError: No module named torch error usually occurs if you trying to import the
torch module, yet it is not installed on your python library or the python interpreter cannot find the installed
torch modules in your system.
What are the cause of error no module named torch?
no module named torch” error usually occurs when the Python interpreter cannot find the PyTorch package/module in your PYTHONPATH environment.
Here are the multiple reasons which are possible causes for this error:
1. PyTorch is not installed:
PyTorch is not installed in your Python environment, you cannot import it. You can install PyTorch module using pip or conda.
2. Incorrect installation path:
PyTorch is installed yet the installation path is not added to the correct PYTHONPATH environment variable, then the Python interpreter unable to find it. Make sure that the installation path is added to the PYTHONPATH environment correctly.
3. Incorrect Python version:
PyTorch requires an exact version of Python to be installed. Make sure that you are using the correct version of Python.
4. Virtual environment issue:
When you are using a
virtual environment and
PyTorch is installed outside the environment, first you must need to
activate the virtual environment or you must installed
PyTorch within the path of virtual environment.
3. Name conflict:
When you have another module with the same name as
PyTorch, it will cause a conflict and it will block the PyTorch from being imported. You will make sure that there are no naming conflicts in your environment.
4. Incorrect Spelling
You need to check the correct spelling of your module name “
torch” in your import statement, so that you can avoid the “
no module named torch” error.
How to solve the error modulenotfounderror: no module named torch?
To solve the error
modulenotfounderror: no module named torch you can follow the steps below:
For Windows Installation
Step 1: Check if the torch is installed
You can check if the
torch is installed on your computer through running the following command in your
pip show torch
After you run the command above, if the result will be like this below it means the torch module is not installed on your system.
So that you need to proceed to the next solutions.
Step 2: Install torch package
Based on step 1 the result shows that the package is not installed, For that, you will install the “Torch” package using pip manager through running the following command:
pip install torch
After you run the command above, it will install the torch package library
If you are using Python 3, you can use pip3 command instead of pip.
pip3 install torch
Step 3: Check the Pip if Torch is installed
torch is already installed, then make sure you are executing your code in the same environment where
torch is installed. You can check the installed packages in your environment with the use of the following command:
pip show torch
If you run the command above if it is installed it will show the following information such as name, version, summary, author and location, etc.
If the error still continues, you can proceed to the next step which Uninstalling and Reinstalling
Step 4: Uninstalling and Reinstalling
If the error still persists, try to uninstall and reinstall the torch module with the use of the following commands:
pip uninstall torch
After you run the command above it will uninstall or remove the torch module in your system then the message will appear like this
Successfully uninstalled torch-1.13.1
For Anaconda Installation
If you are using Anaconda, you can use the following command to install the torch package in your anaconda prompt:
conda install pytorch torchvision torchaudio -c pytorch
If you run the command above it is installed it will show the following information
For Ubuntu Installation
If you are using Ubuntu, you can use the following command to install the torch package in your ubuntu terminal:
sudo apt install torch
For Jupyter Notebook Installation
If you are using Jupyter Notebook, you can use the following command to install the torch package in your Jupyter Notebook terminal:
!pip install torch
you run the command above it is installed it will show the following information
To conclude, we already discuss the solutions to solve the error
Modulenotfounderror no module named torch in different platform such as Windows, Ubuntu, Anaconda, and Jupyter Notebook
