Problem description

read_csv in pandas1.0.4 has stopped working with s3fs.

On pandas1.0.3

import pandas as pd; import s3fs
s3fs.S3FileSystem(anon=False, key=os.environ.get("STORE_USERNAME"), secret=os.environ.get("STORE_PASSWORD"))
df = pd.read_csv(filepath_or_buffer="s3://my-private-bucket/my_dataframe.csv")
print(df.shape)

prints the correct output, whilst using pandas1.0.4 it raises the following exception

[alimcmaster1]

Hi, thanks for the report, does this work with an AWS Credentials File? We made this throw an error when no credentials are defined as per #32486 .

Can you try reading the csv like #16692 (comment) ?

[simonjayhawkins]

@alimcmaster1 @jorisvandenbossche is this a regression in 1.0.4?

[TomAugspurger]

#34626 and this are duplicates. There's discussion over there, so closing this.

@simonjayhawkins it is a regression in 1.0.4, but I don't think a fix has been implemented yet. I'm not sure that we should delay the 1.0.5 release for this.

#34632 - will have fixed this for 1.0.5 @TomAugspurger

[TomAugspurger]

OK thanks.
