Error message

dashscope package not installed. Run: pip install dashscope

What it means

Solutions

1. Run: pip install dashscope
2. Pin dashscope in requirements.txt/pyproject dependencies
3. Rebuild/redeploy the container image with the dependency
4. Verify the installed dashscope version exposes ImageGeneration

Example fix

# before
pip install pixelle-video
# after
pip install pixelle-video dashscope

try:
    import dashscope
    from dashscope import ImageGeneration
except ImportError:
    raise SystemExit("Run: pip install dashscope")

try:
    paths = gen.generate_image(prompt=p)
except RuntimeError as e:
    if "dashscope package not installed" in str(e):
        raise SystemExit("Run: pip install dashscope") from e

When it happens

Trigger: Calling generate_image when the 'dashscope' pip package is absent from the environment (fresh venv, Docker image without the dependency, optional-dependency not installed).

Common situations: Deploying without requirements.txt; using a slim base image; installing a different/older SDK that does not expose ImageGeneration; mixing project venvs.
