Precision and recall values returns 0 for every epochs

[swaminathanayyappan190799]

hi , with the latest code of yolov5. Whenever I did the training for a custom dataset it returns the precision and recall values as 0

Requirements

Python>=3.7.0 with all requirements.txt installed including PyTorch>=1.7. To get started:

git clone https://github.com/ultralytics/yolov5  # clone
cd yolov5
pip install -r requirements.txt  # install

Environments

YOLOv5 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):

• Google Colab and Kaggle notebooks with free GPU:
• Google Cloud Deep Learning VM. See GCP Quickstart Guide
• Amazon Deep Learning AMI. See AWS Quickstart Guide
• Docker Image. See Docker Quickstart Guide

Status

If this badge is green, all YOLOv5 GitHub Actions Continuous Integration (CI) tests are currently passing. CI tests verify correct operation of YOLOv5 training (train.py), validation (val.py), inference (detect.py) and export (export.py) on macOS, Windows, and Ubuntu every 24 hours and on every commit.

hi,

Same here , this was same data set that was trained same day back and the values were coming ( validation precision and recall ) now they don't seem to come or are always 0

[pourmand1376]

How is the distribution of your classes? Is your dataset imbalanced?

[swaminathanayyappan190799]

@pourmand1376, there is a slight imbalance in the classes but eventhough the previous releases of yolov5l have handled these issues perfectly with the current dataset. The problem is actually with the latest build

[pourmand1376]

Hmm. So you can easily switch to the release that you want and use it.

This is very easy with git. Just use git switch.

[arun-gautham]

!git checkout d1dfcab

did the job

[swaminathanayyappan190799]

@pourmand1376 , it worked thanks for your suggestion

[glenn-jocher]

@swaminathanayyappan190799 I've reproduced this issue and am working on it now.

[glenn-jocher]

First commit producing zero output seems to be this, which is really strange as it doesn't affect Detection training.
