# What does this PR do?

I have replaced the assert statements with appropriate exceptions in the directory `src/transformers/models/` with all models beginning with `a` and `b` letters.

Also, I have corrected error handling at places where except statements were handling AssertionError, even thought it was never to be raised. Here is an example:

```
try:
    if pointer.shape != array.shape:
        raise ValueError(f"Pointer shape {pointer.shape} and array shape {array.shape} mismatched")
except AssertionError as e:    # Incorrect line
    e.args += (pointer.shape, array.shape)
    raise
```

I changed the above to:

```
try:
    if pointer.shape != array.shape:
        raise ValueError(f"Pointer shape {pointer.shape} and array shape {array.shape} mismatched")
except ValueError as e:    # Corrected the line
    e.args += (pointer.shape, array.shape)
    raise
```

Fixes #12789
