Check boto3-stubs project for installation and usage instructions.
If you use up-to-date
boto3 version, just install corresponding
boto3-stubs and start
using code auto-complete and
mypy validation. You can find instructions on
This page is only for building type annotations manually. For example, if you want to

How to build type annotations
# Install preferred version of `boto3` python -m pip install boto3==1.16.25 botocore==1.19.25 # Install `mypy-boto3-builder` python -m pip install mypy-boto3-builder # Build all packages in mypy_boto3_output directory python -m mypy_boto3_builder mypy_boto3_output # Or specify required services explicitly python -m mypy_boto3_builder mypy_boto3_output -s ec2 s3 # Install custom `boto3-stubs` packages cd mypy_boto3_output pip install mypy_boto3_ec2_package pip install mypy_boto3_s3_package pip install boto3_stubs_package
With Docker image
- Install Docker
- Pull latest
mypy_boto3_builderversion and tag it
docker pull docker.pkg.github.com/vemel/mypy_boto3_builder/mypy_boto3_builder_stable:latest docker tag docker.pkg.github.com/vemel/mypy_boto3_builder/mypy_boto3_builder_stable:latest mypy_boto3_builder
- Generate stubs in
mkdir output # generate stubs for all services docker run -v `pwd`/output:/output -ti mypy_boto3_builder # generate stubs for s3 service docker run -v `pwd`/output:/output -ti mypy_boto3_builder -s s3 # generate stubs for a specific boto3 version docker run -e BOTO3_VERSION=1.16.25 BOTOCORE_VERSION=1.19.25 -v `pwd`/output:/output -ti mypy_boto3_builder
- Install packages from
outputdirectory as described above
PyCharm consumes too much CPU
PyCharm does not handle
Literal overloads properly, so the only way to reduce CPU usage is to generate
overloads only for services you use
# got to your project folder, activate venv # install boto3-stubs as usual with services you need pip install 'boto3-stubs[s3,ec2]' # install mypy_boto3_builder pip install mypy_boto3_builder # generate boto3 stubs only with services in use, s3 and ec2 in this case # stubs should be generated in <project_root>/typings/boto3 python -m mypy_boto3_builder --installed --skip-services typings -d -s s3 ec2
<project_root>/typings folder to your Interpreter Paths
Autocomplete should work now and do not stress your CPU. Still, try to avoid generation
for 6 or more services, as it is still stressful for PyCharm. In this case, generate
for a couple of services and use explicit type annotations for the rest.
Since stubs are stored in your project root, you do not need to re-generate them after update.
