## TL;DR

The three arrays have to be the same length: one set of logits (and one label) per input. Fix it by giving logits one row per input: logits = [[0.1, 0.9], [0.8, 0.2]]. The classic mistake is passing two inputs and two labels but only one row of logits, e.g. inputs = [text1, text2] with logits = [[0.1, 0.9]] and labels = [1, 0].

## The error

```text
ValueError: Inputs and logits must have the same batch size
```

## Fix

1. The three arrays have to be the same length: one set of logits (and one label) per input.
   Expected: You get the expected result; the problem is gone.
2. Fix it by giving logits one row per input: logits = [[0.1, 0.9], [0.8, 0.2]].
   Expected: You get the expected result; the problem is gone.
3. Re-run the original operation and confirm the error is gone.
   Expected: no error, normal output.

## When to use

- You hit this exact error with Galileo SDK.
- The symptom matches: ValueError: Inputs and logits must have the same batch size.

## When NOT to use

- A different error message from Galileo SDK; the cause here is specific to this error.
- Unrelated Galileo SDK issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Compatibility

Reported against Galileo SDK (mentions 0.1, 0.2, 0.8, 0.9).

## Variant phrasings

### ValueError: Inputs and logits must have the same batch size

## Why it happens

Calling log_model_outputs() throws "ValueError: Inputs and logits must have the same batch size." I passed inputs, logits, and labels. What is mismatched?

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- Behavior can change between releases; the linked source reflects the versions above.
- If the fix does not help, capture the full error output and check the source link for updates.
