To run a Python script in a specific Anaconda virtual environment using a cron scheduler, follow these steps:

1. Create a Shell Script: Write a shell script to activate the virtual environment and run your Python script. Save this script, for example, as `run_script.sh`:

```

  #!/bin/bash
  source /path/to/anaconda/envs/your_env_name/bin/activate
  python /path/to/your_script.py
  deactivate
  ```
  Replace `/path/to/anaconda/envs/your_env_name/` with the actual path to your Anaconda environment and `/path/to/your_script.py` with the path to your Python script.

1. Make the Script Executable: Give the script execute permissions:

```

  chmod +x /path/to/run_script.sh
  ```

1. Edit the Crontab: Open the crontab file to schedule your script:

```

  crontab -e
  ```
  Add a cron job entry to run your script at the desired schedule. For example, to run it every hour, you would add:
  ```
  0 * * * * /path/to/run_script.sh
  ```
  This example runs the script at the beginning of every hour.

1. Save and Exit: Save the crontab file and exit the editor. The cron job is now scheduled to run your script in the specified Anaconda virtual environment.

Note: The `source` command is a Linux shell command used to load a script into the current shell session. It ensures that the environment is set up properly before executing the next commands.
