InternVideo2.5 is a sophisticated video processing framework developed by OpenGVLab. It incorporates advanced AI-driven methodologies for tasks such as frame interpolation, video enhancement, and object tracking.
InternVideo2.5 is an open-source video understanding model that excels at tasks like:
Built on PyTorch, it leverages advanced architectures like Vision Transformers (ViTs) and is pretrained on large datasets for robust performance.
Ensure your Mac meets these requirements:
Component | Minimum Requirement | Recommended |
---|---|---|
macOS Version | macOS 12 Monterey | macOS 13 Ventura or later |
Processor | Intel Core i5 (x64) | Apple Silicon (M1/M2/M3) |
RAM | 8 GB | 16 GB or higher |
Storage | 10 GB free space | 20 GB free space |
Python Version | Python 3.8+ | Python 3.10+ |
For package management, install Homebrew via the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Verify Homebrew installation:
brew --version
To install Python and its package manager:
brew install python
Verify the installation:
python3 --version
pip3 --version
Install requisite Python dependencies, including flash-attention2
:
pip install flash-attention2
Refer to the official documentation for additional dependencies.
Clone the InternVideo2.5 repository from GitHub:
git clone [repository URL]
Navigate to the cloned directory:
cd InternVideo2.5
Define environment variables as per the repository requirements:
export PATH=$PATH:/path/to/internvideo
For systems necessitating PowerShell, install via Homebrew:
brew install powershell/tap/powershell
Verify installation:
pwsh
Download and extract binary archives:
curl -L -o /tmp/powershell.tar.gz https://github.com/PowerShell/PowerShell/releases/download/v7.5.0/powershell-7.5.0-osx-x64.tar.gz
sudo mkdir -p /usr/local/microsoft/powershell/7
sudo tar zxf /tmp/powershell.tar.gz -C /usr/local/microsoft/powershell/7
sudo chmod +x /usr/local/microsoft/powershell/7/pwsh
sudo ln -s /usr/local/microsoft/powershell/7/pwsh /usr/local/bin/pwsh
Ensure appropriate path configurations:
$PSHOME
should be /usr/local/microsoft/powershell/7
~/.config/powershell/profile.ps1
~/.local/share/powershell/Modules
Execute the model using the following command:
python run_inference.py --input_video video.mp4 --output_dir output
To facilitate large-scale processing:
import os
import subprocess
video_folder = "input_videos"
os.makedirs("output_videos", exist_ok=True)
for video_file in os.listdir(video_folder):
input_path = os.path.join(video_folder, video_file)
command = f"python run_inference.py --input_video {input_path} --output_dir output_videos"
subprocess.run(command, shell=True)
Adjust inference parameters dynamically:
python run_inference.py --input_video video.mp4 --output_dir output --model_quality high --frame_rate 60
For computational efficiency, leverage multiprocessing:
from multiprocessing import Pool
def process_video(video_file):
command = f"python run_inference.py --input_video {video_file} --output_dir output"
os.system(command)
video_files = ["video1.mp4", "video2.mp4", "video3.mp4"]
with Pool(3) as p:
p.map(process_video, video_files)
Solution: Reinstall flash-attention2
with compatible CUDA/cpu ops:
pip uninstall flash-attention2
pip install flash-attention2 --no-build-isolation
Solution: Limit GPU memory usage:
import os
os.environ["PYTORCH_MPS_HIGH_WATERMARK_RATIO"] = "0.5"
Solution: Install FFmpeg via Homebrew:
brew install ffmpeg
Utilize macOS Metal API for GPU-based acceleration.
Experiment with batch sizes, video resolution, and processing threads for efficiency gains.
By adhering to this structured methodology, users can install and deploy InternVideo2.5 on macOS. Continuous monitoring of updates and best practices ensures optimal model performance for advanced video processing applications.
