Input sizes bigger than 512 tokens

[SSamDav]

I tried to run the eval script on the baseball_1 and cre_Drama_Workshop_Groups DBs, however, I got an error related to the input size.
How do you overcome this error?

Do you have more details on this? including the command you run, the error you get, etc.

I run your notebook with the DBs that I mentioned and i get this error:

So the code is the following one:

db_id = "baseball_1"
my_schema = dump_db_json_schema("data/sqlite_files/{db_id}/{db_id}.sqlite".format(db_id=db_id), db_id)
schema, eval_foreign_key_maps = load_tables_from_schema_dict(my_schema)
dataset = registry.construct('dataset_infer', {
   "name": "spider", "schemas": schema, "eval_foreign_key_maps": eval_foreign_key_maps, 
    "db_path": "data/sqlite_files/"
})

for _, schema in dataset.schemas.items():
    model.preproc.enc_preproc._preprocess_schema(schema)

spider_schema = dataset.schemas[db_id]

def infer(question):
    data_item = SpiderItem(
            text=None,  # intentionally None -- should be ignored when the tokenizer is set correctly
            code=None,
            schema=spider_schema,
            orig_schema=spider_schema.orig,
            orig={"question": question}
        )
    model.preproc.clear_items()
    enc_input = model.preproc.enc_preproc.preprocess_item(data_item, None)
    preproc_data = enc_input, None
    with torch.no_grad():
        output = inferer._infer_one(model, data_item, preproc_data, beam_size=1, use_heuristic=True)
    return output[0]["inferred_code"]

code = infer("How many players are there?")
print(code)
