Where example.txt should be the file we want to download – in our case, we need to replace this with the path to our weights file. How do you download a file from Google Colab? It's this simple: from lab import filesįiles.download('example.txt') How to download files from Google Colab to your computer. We recommend saving weights to your Google Drive. Once we have the file path of our weights file, we can save this file locally or to our Google Drive. (PRO TIP: To identify the file path of any file in Colab, you can use the navigation pane on the left, right click a given file, and select, "Copy file path.") Weights folder in Google Colab Download the Weights from Colab (Locally or to Google Drive) content/yolov5/runs/exp0_yolov5s_results/weights/best.pt In our example YOLOv5 notebook, these weights are saved in the runs folder. Identify the Weights File PathĪfter training a model, the weights of that model are stored as a file in the Colab session. To save model weights, we must first have weights we want to save and a destination where we seek to save those weights. In this post, we walkthrough how to save and reload model weights from YOLOv5 in the notebook from the Roboflow Model Library, but the steps we follow are applicable to any Colab session (with file path modification). Reloading the model weights means using those saved weights in a future experiment – even if that is a new session in Colab. Saving a model's weights means saving the fit of a model after training. the user is not active in that tab) for an hour, the kernel disconnects.īecause of this, it's important to save a model's weights and reload them in a future session. If the browser session senses inactivity (e.g. The compute resources allocated are limited to a 12-hour span. For this reason, the Roboflow Model Library includes many free, open source computer vision models available on Google Colab.Ĭolab does come with limitations. Google Colab is Google's hosted Jupyter Notebook product that provides a free compute environment, including GPU and TPU.Ĭolab comes "batteries included" with many popular Python packages installed, making it a choice tool for easy model experimentation.
