# 2. Check Python Environment:

Make sure you are using the correct Python environment where Vortex is installed. If you are using virtual environments, activate the correct one:

For virtualenv:

```bash

source path_to_your_env/bin/activate

```

For conda:

```bash

conda activate your_env_name

```
