输入图片不存在: {image_path}

Error message

输入图片不存在: {image_path}

What it means

generate_video validates all input file paths up front and raises FileNotFoundError if the primary input image does not exist. This fail-fast check avoids sending a bad request to the API. Only raised when image_path was provided and os.path.exists returns False.

Solutions

  1. os.path.exists(image_path) check before calling and correct/resolve the path
  2. Convert to absolute path (os.path.abspath / pathlib.Path.resolve) to avoid cwd mismatch
  3. Ensure the upstream step that produces the image completed successfully
  4. In containers, verify the directory is volume-mounted and readable

Example fix

// before
client.generate_video(prompt, image_path='outputs/img.png')  # FileNotFoundError
// after
from pathlib import Path
img = Path('outputs/img.png').resolve()
assert img.exists(), f"missing {img}"
client.generate_video(prompt, image_path=str(img))
Defensive patterns

Strategy: validation

Validate before calling

import os
if image_path and not os.path.exists(image_path):
    raise FileNotFoundError(f'输入图片不存在: {image_path}')

Type guard

def is_existing_file(path) -> bool:
    return isinstance(path, str) and os.path.isfile(path)

Try / catch

try:
    video = client.generate_video(prompt, image_path=image_path)
except FileNotFoundError as e:
    logging.error(f'Input image missing: {e}')
    video = None  # or regenerate the image first

Prevention

When it happens

Trigger: generate_video(image_path='/path/img.png', ...) where that file does not exist — deleted file, wrong relative path, or path built from user input.

Common situations: Relative vs absolute path confusion (working directory differs in production); file generated by a previous pipeline step that failed silently; image uploaded later than the video call; container not mounting the volume containing the image.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
