Hi,
I’m running a self-hosted Retool instance on an EC2 instance with Docker Compose, and I’m trying to add external Python libraries (e.g., mem0) in the Workflows section. In the Libraries tab, I see the option to "Add Python library" alongside "Add JavaScript library," and I have JavaScript libraries listed (e.g., lodash, numbro). However, when I click "Add Python library," there’s no interface to add external packages or edit a requirements.txt file—only pre-installed Python packages (if any) are shown, but no option to include new ones like mem0.
The Retool docs mention that the code-executor needs to run in privileged mode for NsJail to handle Python execution, and I’ve set privileged: true in my docker-compose.yml. Here’s my code-executor config:
code-executor:
build:
context: ./
dockerfile: CodeExecutor.Dockerfile
command: bash -c "./start.sh"
env_file: ./docker.env
environment:
- DEPLOYMENT_TEMPLATE_TYPE=docker-compose
- NODE_OPTIONS=--max_old_space_size=1024
networks:
- code-executor-network
privileged: true
restart: on-failure
- My CodeExecutor.Dockerfile is based on the default Retool setup (not modified).
- The CODE_EXECUTOR_INGRESS_DOMAIN is set to http://code-executor:3004 in other services.
- Workflows are enabled, and I can use Python Code blocks.
- Retool version: 3.33.31
Why isn’t the option to add external Python libraries (e.g., via requirements.txt) appearing, even with the "Add Python library" button? Is this a configuration issue, a version limitation, or something else? Has anyone else seen this behavior with a similar EC2/Docker Compose setup? Any guidance would be appreciated!
Thanks.
is upgrading your Retool instance an option for you? If so, I recommend upgrading to 3.114 or 3.148 to get access.
