1. Python Errors

modulenotfounderror no module named ‘nets’

nets provides a basic neural network structure so you can create your own with numpy. You will need to wrap your arrays in a Tensor class to keep track of the gradients, just like in PyTorch.

The Python ModuleNotFoundError: No module named ‘nets’ occurs when we forget to install the nets module before importing it or installed it in an incorrect environment. To solve the error, install the module by running the pip install nets command.

how to fix modulenotfounderror no module named nets

Open your terminal in your project’s root directory and install the nets module.

# 👇️ in a virtual environment or using Python 2
pip install nets

# 👇️ for python 3 (could also be pip3.10 depending on your version)
pip3 install nets

# 👇️ if you get permissions error
sudo pip3 install nets

# 👇️ if you don’t have pip in your PATH environment variable
python -m pip install nets

# 👇️ for python 3 (could also be pip3.10 depending on your version)
python3 -m pip install nets

# 👇️ for Anaconda
conda install -c conda-forge nets

The Python error “ModuleNotFoundError: No module named nets” occurs for multiple reasons:

  1. Not having the nets package installed by running pip install nets.
  2. Installing the package in a different Python version than the one you’re using.
  3. Installing the package globally and not in your virtual environment.
  4. Your IDE running an incorrect version of Python.
  5. Naming your module nets.py which would shadow the official module.
  6. Declaring a variable named nets which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

# 👇️ Checking version of python
python –version

For example, my Python version is 3.10.4

So I would install the nets package with pip3.10 install nets

pip3.10 install nets

# 👇️ if you get permissions error use pip3 (NOT pip3.X)
sudo pip3 install nets

Notice that the version number corresponds to the version of pip I’m using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip.

# 👇️ make sure to use your version of Python, e.g. 3.10
python3 -m pip install nets

If the “No module named nets” error persists, try restarting your IDE and development server / script.

You can check if you have the nets package installed by running the pip show nets command.

# 👇️ check if you have nets installed
pip3 show nets

# 👇️ if you don’t have pip setup in PATH
python3 -m pip show nets

The pip show nets command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

If you are using a virtual environment, make sure you are installing nets in your virtual environment and not globally.

You can try creating a virtual environment if you don’t already have one.

# 👇️ use correct version of Python when creating VENV
python3 -m venv venv

# 👇️ activate on Unix or MacOS
source venv/bin/activate

# 👇️ activate on Windows (cmd.exe)
venv\Scripts\activate.bat

# 👇️ activate on Windows (PowerShell)
venv\Scripts\Activate.ps1

# 👇️ install nets in virtual environment
pip install nets

Your virtual environment will use the version of Python that was used to create it.

If the error persists, make sure you haven’t named a module in your project as nets.py because that would shadow the original nets module.

You also shouldn’t be declaring a variable named nets as that would also shadow the original module.

If the error is not resolved, try to uninstall the nets package and then install it.

# 👇️ check if you have nets installed
pip3 show nets

# 👇️ if you don’t have pip set up in PATH
python3 -m pip show nets

# 👇️ uninstall nets
pip3 uninstall nets

# 👇️ if you don’t have pip set up in PATH
python3 -m pip uninstall nets

# 👇️ install nets
pip3 install nets

# 👇️ if you don’t have pip set up in PATH
python3 -m pip install nets

Try restarting your IDE and development server/script.

You can also try to upgrade the version of the nets package.

pip3 install nets –upgrade

# 👇️ if you don’t have pip set up in PATH
python3 -m pip install nets –upgrade

Conclusion

The Python “ModuleNotFoundError: No module named nets” occurs when we forget to install the nets module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install nets command.
