Install the Castor EDC API package

To install software and to open internet ports, you need Owner rights in a workspace.
  1. Connect to a VM.
  2. Install and configure the appropriate tools such as Python and Anaconda (Python, Miniconda, Jupyterlab & Python Packages).
  3. Install the Castor EDC API package by following the instructions here:
  4. Information on how to get your Castor client ID and secrets can be found below.
We advise to use conda install rather than pip install when working in a myDRE workspace.  VMs on myDRE do not have internet access by default. Owners of workspaces can create external access rules to access certain IP addresses, however, these are limited to static IP addresses. PIP uses PyPi which makes use of dynamic IP addresses. Conversely, Anaconda is hosting their package repositories on a static IP address.

The same package can also be used in R. Please visit for more information. Please refer to Python, Miniconda, Jupyterlab & Python Packages on how to install Miniconda.
