Hello,

I created a collection for all my roles for the homelab and defined a requirements.yml for the ansible collections and a requirements.txt for the python packages.  
Unfortunately the python package dependencies are ignored during install (collections are ok)

My collection structure:

```bash
projects/mcchaos.homelab/
├── README.md
├── docs
├── galaxy.yml
├── meta
│ ├── execution-environment.yml
│ ├── requirements.txt
│ └── runtime.yml
├── plugins
│ ├── README.md
│ ├── filter
│ │ └── my_filters.py
│ └── modules
│ └── proxmox_replication.py
├── requirements.txt
└── roles
    ├── pve_backup
    │ └── tasks
    │ └── main.yml
    ├── restic_pull
    │ ├── tasks
    │ │ └── main.yml
    │ ├── templates
    │ │ └── restic-pull.sh
    │ └── tests
    │ └── test_restic_pull.yml
    └── ...

```

The execution-environment.yml:

```yaml
# code: language=yaml
version: 3

dependencies:
  python: meta/requirements.txt

```

The requirements.txt:

```auto
proxmoxer>=2.0
jmespath
requests
httpx
dnspython
netaddr
passlib
ssh-audit
python-debian

```

Check the dependencies:

```bash
$ ansible-builder introspect projects/mcchaos.homelab/
# Dependency data for projects/mcchaos.homelab/
---
python: []
system: []

$ 

```

Install the collection:

```bash
$ ansible-galaxy collection install --force projects/mcchaos.homelab

```

I tried already several tutorials but unfortunately it’s still not working.  
What do I need to configure, that together with the collection all python packages will be installed?

Thanks a lot 🙂  
Thomas

The Python requirements are only installed when building an Execution Environment with ansible-builder. `ansible-galaxy collection install` simply **never** installs Python requirements.
