SadTalker AI Error: Failed in Loading audio2pose_checkpoint

When working with SadTalker AI, you might encounter an error related to loading the audio2pose_checkpoint. This can be frustrating, but it is often due to issues with file paths, missing files, or incomplete downloads. Here’s a step-by-step guide to help you troubleshoot and resolve this issue.

Step-by-Step Solutions:

1. Check File Path

The first step is to ensure that the file path to the audio2pose_checkpoint is correct.


  • Locate the audio2pose_checkpoint file on your system.
  • Verify that the path specified in your code matches the location of the file.


checkpoint_path = "path/to/SADTALKER_CHECKPOINTS/audio2pose_checkpoint.pth"

Ensure the directory structure and file names are correct.

2. Download Checkpoints

If the audio2pose_checkpoint file is missing or you suspect it might be corrupted, re-download all the necessary checkpoints.


  • Download the checkpoints from this link.
  • Place all downloaded files into the SADTALKER_CHECKPOINTS directory.
  • Verify that all necessary files are present.


Navigate to the directory where you want to store the checkpoints:

  mkdir -p path/to/SADTALKER_CHECKPOINTS

Download the checkpoints (replace with actual URLs or methods provided by the SadTalker AI documentation):

  # Repeat for other required checkpoints

3. Redownload wav2lip.pth

Sometimes the wav2lip.pth file might not be fully downloaded, leading to issues. Re-download this file to ensure it’s complete.


  • Remove the existing wav2lip.pth file if it exists:
  rm path/to/SADTALKER_CHECKPOINTS/wav2lip.pth
  • Re-download the wav2lip.pth file from the official source.


  • Download the file (replace with actual URL):

4. Verify File Integrity

Ensure that all checkpoint files are correctly downloaded and not corrupted.


  • Compare the file sizes with those listed on the download page.
  • Use checksums if provided to verify file integrity.


  • Check the file size:
  • Verify checksum (if provided):
  sha256sum path/to/SADTALKER_CHECKPOINTS/audio2pose_checkpoint.pth

5. Correct File Loading Method

Verify that the method used to load the checkpoint is correct and compatible with the file format.


If using PyTorch, ensure you are using the torch.load function properly:

import torch

checkpoint_path = "checkpoints/audio2pose_checkpoint.pth"
    checkpoint = torch.load(checkpoint_path)
except Exception as e:
    print(f"Failed to load checkpoint: {e}")

6. Check Dependencies and Versions

Ensure that the version of the libraries you are using (e.g., PyTorch) is compatible with the checkpoint file.


  • Check the version of PyTorch or any other library you are using.
  • Upgrade or downgrade to the version specified by the SadTalker AI documentation.

For PyTorch:

pip install torch==1.8.0  # Replace with the version required

7. Permissions and Access

Ensure that the file and directory have the necessary permissions for reading.


Check file permissions and change if necessary:

chmod 644 checkpoints/audio2pose_checkpoint.pth

8. Documentation and Community

If the issue persists, consult the SadTalker AI documentation and community forums. There might be known issues or updates.


  • Visit the official SadTalker GitHub repository or website.
  • Check the issues section for similar problems.
  • Post a new issue if needed, providing details of the error and steps you’ve taken.

Example Code to Load Checkpoint

After ensuring that the file paths are correct and the files are intact, use the following example to load the checkpoint in your code:

import torch
import os

# Define the checkpoint path
checkpoint_path = "path/to/SADTALKER_CHECKPOINTS/audio2pose_checkpoint.pth"

# Check if file exists
if not os.path.exists(checkpoint_path):
    raise FileNotFoundError(f"Checkpoint file not found: {checkpoint_path}")

# Attempt to load the checkpoint
    checkpoint = torch.load(checkpoint_path)
    print("Checkpoint loaded successfully")
except Exception as e:
    print(f"Failed to load checkpoint: {e}")
    # Additional error handling or fallback logic can be added here

Final Thoughts

By following these steps, you should be able to resolve the issue with loading the audio2pose_checkpoint in SadTalker AI. Ensure that all file paths are correct, necessary files are downloaded and intact, and the method of loading the checkpoint is appropriate.
