[Bug] Num retry not working?

[AashiqRamachandran-bf]

What happened?

When I try to use sonnet 3.7 on bedrock, I keep getting LiteLLM error ssaying rate limit reached, even when num_rety is set to 50.

lm = dspy.LM(
model="bedrock/us.anthropic.claude-3-7-sonnet-20250219-v1:0",
temperature=1.0,
max_tokens=8000,
num_retries=50
)

Not sure if I am doing anything wrong. Is there a better way to dynamically backoff?

Steps to reproduce

lm = dspy.LM(
model="bedrock/us.anthropic.claude-3-7-sonnet-20250219-v1:0",
temperature=1.0,
max_tokens=8000,
num_retries=50
)
dspy.configure(lm)
