Common Errors

ModuleNotFoundError2 reports

This error usually means that Python can't find a required module, often due to an incomplete or corrupted installation. Try reinstalling InvokeAI using `pip install --upgrade --force-reinstall invokeai` to ensure all dependencies are correctly installed. If using a virtual environment, make sure it is activated before the reinstall.

DuplicateModelException2 reports

The DuplicateModelException in InvokeAI arises when attempting to save different models or model variants to the same destination file path, often during starter model installation or custom model import processes. To resolve this, ensure each model is assigned a unique name and that the destination paths specified for saving models (filenames) are distinct, preventing write conflicts and allowing successful model storage. Double check for name clashes in your models.yaml file, renaming as needed.

MaxRetryError2 reports

MaxRetryError in InvokeAI usually arises from network connectivity issues preventing the application from accessing necessary online resources like model files or external APIs. Ensure you have a stable internet connection and that no firewall or proxy settings are blocking InvokeAI's access. If using custom models or APIs, double-check their URLs for correctness and availability and configure InvokeAI to use a valid proxy if required.

NewConnectionError1 report

NewConnectionError usually indicates invokeai is trying to access an online resource (model, VAE, etc.) but cannot connect to the internet. Ensure you have a stable internet connection and that no firewalls or proxies are blocking InvokeAI's access. If a specific model is causing the issue, try downloading it manually and placing it in the correct InvokeAI models directory.

UnknownModelException1 report

The "UnknownModelException" often arises from corrupted or missing model files in InvokeAI's models directory or inconsistencies between the configuration file and available models. To resolve this, first, verify the integrity of your model files by re-downloading them, ensuring correct placement in the InvokeAI models directory. Then, refresh the InvokeAI model list using the `invokeai-configure` command, selecting "N" (no custom path) to ensure the standard models path is properly configured.

UnicodeDecodeError1 report

UnicodeDecodeError usually arises when trying to decode a file or stream with an encoding different from what was used to encode it. Specify the correct encoding when opening files or decoding byte strings, often 'utf-8' or 'latin-1', using the `encoding` parameter in functions like `open()` or the `.decode()` method (e.g., `open('file.txt', 'r', encoding='utf-8')` or `byte_string.decode('latin-1')`). If the correct encoding is unknown, try different common encodings until the error disappears.
