Debug

Known issues

breakingIn version 0.40.0+, the import path for agents changed from `ldp import Agent` to `from ldp.agent import Agent`. Old imports will raise ModuleNotFoundError.

fix

Use `from ldp.agent import Agent`.

affects: <0.40.0

breakingThe `Graph` class was moved from `ldp` to `ldp.graph` in version 0.35.0.

fix

Use `from ldp.graph import Graph`.

affects: <0.35.0

deprecatedThe `memory` module is being replaced by `store` for persistent memory backends. The `ldp.memory` API is considered legacy and will be removed in a future release.

fix

Use `from ldp.store import ...` instead of `from ldp.memory import ...`.

affects: >=0.40.0

gotchaLDP requires Python 3.11+. Installing on older Python versions will fail with an unsupported version error.

fix

Ensure Python 3.11 or later is used.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'ldp'

LDP is not installed or installed in a different environment.

fix

Run `pip install ldp` in the correct Python environment.

ModuleNotFoundError: No module named 'ldp.agent'

Using an outdated import path (e.g., `import ldp.Agent`).

fix

Use `from ldp.agent import Agent` (requires ldp>=0.40.0).

ImportError: cannot import name 'Memory' from 'ldp.memory'

Memory class was removed or renamed in newer versions.

fix

Check your ldp version and use `from ldp.store import MemoryStore` if on latest (or use legacy version).
