Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

FunctionExecutor

✓ from lithops import FunctionExecutor

✗ from lithops.executor import FunctionExecutor

FunctionExecutor is exposed directly from lithops.

Storage

✓ from lithops.storage import Storage

Commonly imported from lithops.storage.

ibm_cf

✓ from lithops import ibm_cf

✗ import ibm_cf

ibm_cf is a module within lithops, not a top-level package.

Basic example: define a function, invoke it asynchronously via Lithops, and retrieve the result.

from lithops import FunctionExecutor def hello(name): return f'Hello {name}!' fexec = FunctionExecutor() fexec.call_async(hello, 'World') result = fexec.get_result() print(result)

lithops --version

Debug

Known issues

gotchaFunctionExecutor is not a context manager; you must call .get_result() or .wait() to ensure the execution completes. Failing to do so may result in uncollected futures.

fix

Always call .get_result() or .wait() on the returned future.

affects: all

breakingIn lithops 3.4.0, AWS and IBM dependencies were moved to extras (lithops[aws], lithops[ibm]). Installing without extras will no longer include boto3 or ibm-cos-sdk.

fix

Install with extras: pip install lithops[aws] or pip install lithops[ibm].

affects: >=3.4.0

gotchaWhen using functools.partial with call_async or map, ensure the partial object is pickleable. Lithops serializes the function and arguments.

fix

Use a wrapper function or ensure the partial is picklable. Version 3.6.4 improved support.

affects: <=3.6.3

deprecatedPassing access and secret keys directly in config for AWS is deprecated since lithops 3.3.0. Use IAM roles or environment variables.

fix

Configure AWS credentials via AWS CLI or environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY).

affects: >=3.3.0

gotchaDefault monitoring interval may cause 'KeyError: 'monitoring_interval'' if not set correctly (fixed in 3.5.0).

fix

Upgrade to lithops>=3.5.0 or explicitly set monitoring_interval in config.

affects: <3.5.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'boto3'

Missing AWS dependencies; lithops requires boto3 for AWS backends.

fix

Install lithops with AWS extras: pip install lithops[aws]

ibm_boto3 and ibm-cos-sdk are missing

IBM Cloud dependencies are not installed.

fix

Install lithops with IBM extras: pip install lithops[ibm]

KeyError: 'monitoring_interval'

Configuration missing monitoring_interval key in older versions.

fix

Upgrade lithops to >=3.5.0 or add 'monitoring_interval' to your lithops config.

AttributeError: 'Future' object has no attribute 'result'

Calling .result() on a Lithops future instead of .get_result() or using the future returned by call_async incorrectly.

fix

Use fexec.get_result() on the executor or call .result() on the future after .wait().
