input-dependent resource specification fails #2555
Description
Snakemake version
v8.0.1
Describe the bug
Lambda functions to define resources (runtime, mem or mem_mb) are not supported. For example, this code works:
resources:
runtime = lambda w: "2 h",
but this fails:
resources:
runtime = lambda w, attempt: f"{2 * attempt} h",
and also this:
resources:
runtime = lambda w, attempt, input: f"{2 * attempt * input.size_mb} h",
Might be related to #2510 and #2423.
Logs
WorkflowError:
Cannot parse mem or disk value into size in MB for setting mem_mb resource: <TBD>
