Use the compression parameter instead.

fin = smart_open.open("/path/file.gz", ignore_ext=True)  # 🚫 No
fin = smart_open.open("/path/file.gz", compression="disable")  # Yes

fin = smart_open.open("/path/file.gz", ignore_ext=False)  # 🚫 No
fin = smart_open.open("/path/file.gz")  # Yes
fin = smart_open.open("/path/file.gz", compression="infer_from_extension")  # Yes, if you want to be explicit

fin = smart_open.open("/path/file", compression=".gz")  # Yes

5.1.0, 25 May 2021

This release introduces a new top-level parameter: compression.
It controls compression behavior and partially overlaps with the old ignore_ext parameter.

3.0.0, 8 Oct 2020

This release modifies the behavior of setup.py with respect to dependencies.
Previously, boto3 and other AWS-related packages were installed by default.
Now, in order to install them, you need to run either:

pip install smart_open[s3]

to install the AWS dependencies only, or

pip install smart_open[all]

to install all dependencies, including AWS, GCS, etc.

2.2.1, 1 Oct 2020

• Include S3 dependencies by default, because removing them in the 2.2.0 minor release was a mistake.

2.2.0, 25 Sep 2020
