How to get simple inference result as txt

Question

I am trying to inference on a batch of images in a directory. The basic inference code is the one used , I have already read the documentation for the Detections return, is there any way to get the detected objects as .txt ? In a similar way to result.print() , it shows the objects and the times they appear.

I am aware that detect.py can save as .txt but couldn't do inference on batch of images with it.


model = torch.hub.load('ultralytics/yolov5', 'yolov5s')

# Images
directory = 'keyframes/'

frames = [] # batch of images
for filename in os.listdir(directory):
    frame = Image.open('keyframes/'+filename)
    frames.append(frame)

# Inference
results = model(frames, size=640) 

# Results
results.print()
results.save()  ```

What I need is the objects detected in a .txt file without using detect.py, but if detect.py can be modified to work on batch of images from a directory that would also work.

@kzhenzhou that's funny, you are right there is no --save-txt method for PyTorch Hub models. You could submit a PR to add such a method, i.e.:

results.save_txt()

https://github.com/ultralytics/yolov5/blob/bd815d48df18a23e2bb08d88e430183bfb48eb78/models/common.py#L551-L650

I'll add a TODO here since this seems like a useful feature to have, but we are quite busy so I can not provide an estimated implementation timeline if we do this ourselves.

TODO: results.save_txt() method.

@glenn-jocher I want to work on this if it's ok?

@SarperYurttas awesome, yes go for it!

Hi @glenn-jocher,

is there anyway to get the heading of the result type saved as well in the output files?

for example:

epoch	loss	acc	val_loss	val_acc

Currently, in the save files the data is presented as the example below without headings in .txt format 0 1.64137483 0.27450982 0.8043378 0.46153846

I tried --save-txt with save --save-conf but none is presenting the headings for the processing results...

I am trying to do a basic decision process but these bits are not available!

Thanx for responding and acknowledging my digital presence, really appreciate this!

@Symbadian Thanks for reaching out! We appreciate your support and contribution to the YOLOv5 community. Currently, the --save-txt option does not include column headings in the saved .txt file. However, you can easily manipulate the .txt file after saving it to include headings using any text manipulation tool or a simple script. We appreciate your understanding and contributions. Good luck with your work!
