A Python client for JuiceFS operations with easy-to-use interfaces and AWS credentials support.

Installation

pip install juicefs-client

Quick Start

Initialize Client

from juicefs_client import JuiceFSClient

# Using environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
client = JuiceFSClient(volume="myvolume", token="mytoken")

# Or with explicit credentials
client = JuiceFSClient(
    volume="myvolume",
    token="mytoken",
    access_key="your-aws-access-key",
    secret_key="your-aws-secret-key"
)

Basic File Operations

# Write and read text files
client.write_file("/path/to/file.txt", "Hello World")
content = client.read_file("/path/to/file.txt")

# Binary files (e.g., PyTorch models)
client.save_torch_model("/models/model.pt", model.state_dict())
state_dict = client.load_torch_model("/models/model.pt")

# List directory contents
files = client.list_dir("/path/to/directory")

# Delete files
client.delete_file("/path/to/file.txt")

# Copy files
client.copy_file("/source/path", "/destination/path")

Features
