Verified usage

Verified import paths — ran on the pinned version, not inferred.

get_model

✓ from pytorchcv.model_provider import get_model

get_model is the primary function to load any model by name.

Quickstart: load a pretrained ResNet-18 model and run inference on a random tensor.

import torch from pytorchcv.model_provider import get_model model = get_model('resnet18', pretrained=True) model.eval() x = torch.randn(1, 3, 224, 224) with torch.no_grad(): out = model(x) print(out.shape)

Debug

Known issues

gotchaModel names are case-sensitive and must match exactly the keys in model_provider (e.g., 'resnet18' works, 'ResNet18' does not).

fix

Use lowercase names; check available models via pytorchcv.model_provider.get_model_list().

affects: all

deprecatedSome older model APIs (e.g., direct import of model classes from pytorchcv.models) may be deprecated in future releases. Use get_model() for future compatibility.

fix

Replace direct class imports with get_model('model_name').

affects: >=0.0.50

gotchaPretrained weights download from a remote server; if the server is down or slow, model loading may fail or hang. There is no fallback or mirror.

fix

Set environment variable PYTORCHCV_CACHE_DIR to customize cache location; consider pre-downloading weights.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'pytorchcv'

Package not installed or installed in wrong environment.

fix

Run: pip install pytorchcv

KeyError: 'resnet18'

Using incorrect model name (case or spelling).

fix

Check list of models: from pytorchcv.model_provider import get_model_list; print(get_model_list())

AttributeError: 'NoneType' object has no attribute 'shape'

Model returned None because pretrained weights failed to load (network issue).

fix

Ensure internet connection or set pretrained=False to load architecture without weights.
