ModuleNotFoundError: No module named 'going_modular'

[NaiyerRafique]

In the paper replicating code when I write the following:

# For this notebook to run with updated APIs, we need torch 1.12+ and torchvision 0.13+
try:
    import torch
    import torchvision
    assert int(torch.__version__.split(".")[1]) >= 12, "torch version should be 1.12+"
    assert int(torchvision.__version__.split(".")[1]) >= 13, "torchvision version should be 0.13+"
    print(f"torch version: {torch.__version__}")
    print(f"torchvision version: {torchvision.__version__}")
except:
    print(f"[INFO] torch/torchvision versions not as required, installing nightly versions.")
    !pip3 install -U torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu113
    import torch
    import torchvision
    print(f"torch version: {torch.__version__}")
    print(f"torchvision version: {torchvision.__version__}")

I get the following error:

Importing the helper_functions works but somehow the going_modular is constantly giving an error. Can you tell me what is wrong?

Hi @NaiyerRafique ,

This is strange.

I just re-ran Notebook 08 - PyTorch Paper Replicating in Google Colab and found it worked.

I was able to download the going_modular scripts as well as import various helper functions.

Where are you running the code?

# Continue with regular imports
import matplotlib.pyplot as plt
import torch
import torchvision

from torch import nn
from torchvision import transforms

# Try to get torchinfo, install it if it doesn't work
try:
    from torchinfo import summary
except:
    print("[INFO] Couldn't find torchinfo... installing it.")
    !pip install -q torchinfo
    from torchinfo import summary

# Try to import the going_modular directory, download it from GitHub if it doesn't work
try:
    from going_modular.going_modular import data_setup, engine
    from helper_functions import download_data, set_seeds, plot_loss_curves
except:
    # Get the going_modular scripts
    print("[INFO] Couldn't find going_modular or helper_functions scripts... downloading them from GitHub.")
    !git clone https://github.com/mrdbourke/pytorch-deep-learning
    !mv pytorch-deep-learning/going_modular .
    !mv pytorch-deep-learning/helper_functions.py . # get the helper_functions.py script
    !rm -rf pytorch-deep-learning
    from going_modular.going_modular import data_setup, engine
    from helper_functions import download_data, set_seeds, plot_loss_curves
