the error loading large parquet file

[peiliu0408]

as mention on here, failed to load the LA_RLHF.parquet (about 22GB) file, which is downloaded from shared Onedrive.

Error msg: pyarrow.lib.ArrowCapacityError: array cannot contain more than 2147483646 bytes, have 2368257792.

is there special way or python package required to load this large (image base64) parquet file?

ohh I am not sure why this happens, my pandas version is 2.1.2. I am using pandas.read_parquet to open parquet files.

[peiliu0408]

The same error msg showing again. I have tried on ubuntu20.04, and get the same error.

I am wondering there are some errors happens when downloading.

[peiliu0408]

Or, can you give a llava-RLHF dataset download link, which is census with your Onedrive file? I just create a new image parquet using the same format.

[Luodian]

Can you try with LLAVAR or LRV? I uploaded them as well.

[Luodian]

LLAVA-RLHF seems correct at my side. I will update it but the previous version should be correct. It's weird.

[peiliu0408]

thanks a lot.

this two parquet file could be opened correctly.

I am sure that LLaVA-RLHF shared in Onedrive checkpoint is damaged, while all rest could be loaded correctly.

I am putting an updated LA_RLHF.parquet file from our server (this is supposedly correctly working for our runs) to OneDrive. May take a few hours, stay tuned tmr maybe. Thanks!

Still not correct

you need use dask:

import dask.dataframe as dd
import json
import pandas as pd

# Load the JSON data
json_file_path = "LA.json"
with open(json_file_path, "r") as f:
    data_dict = json.load(f)

# Convert the dictionary to a Dask DataFrame
ddf = dd.from_pandas(pd.DataFrame.from_dict(data_dict, orient="index", columns=["base64"]), npartitions=10)

# Convert to Parquet
parquet_file_path = 'LA.parquet'
ddf.to_parquet(parquet_file_path, engine="pyarrow")


ddf = dd.read_parquet(parquet_file_path, engine="pyarrow")
search_value = 'LA_IMG_000000377944'
filtered_ddf = ddf.loc[search_value].compute()

which solved this problem.

You can see current code to see if it helps, we changed it to iteratively loading. https://github.com/Luodian/Otter/blob/3a746889cb0d774659f67a49c874100b226c9c94/pipeline/mimicit_utils/mimicit_dataset.py#L222-L229

Previously on both of my 2A100 and 8A100 instances, I could directly load >100GB parquet. But it's weird that I cant do it on another 8*A100-40G instance...
