[iammohit1311]

I am trying to load my custom YOLOv5 model using PyTorch. Then run predictions and save cropped results. However, it seems Chaquopy is not able to read my model named 'best.pt' present in 'assets' directory @mhsmith

Chaquopy version

id 'com.chaquo.python' version '14.0.2' apply false

Relevant parts of my code

This is what I have in my python file:

import torch
model = torch.hub.load('ultralytics/yolov5', 'custom', path='../assets/best.pt', force_reload=True)
im = img_url  

# Inference
results = model(im)

# Results
results.crop(save_dir="./result")  # or .show(), .save(), .crop(), .pandas(), etc.

Describe your issue

The current directory could be anywhere on Android, so you must use absolute paths. See the FAQ sections "Read files in Python" and "Write files in Python".

@iammohit1311 i am getting the same issue........ is your issue resolved? are you able to use Yolov5 model

[mhsmith]

Just follow the instructions in the FAQ, as linked above.
