🔨 Installation

Info

TruLens now operates on OpenTelemetry traces. Read more.

TruLens supports Python 3.10 through 3.14. Three packages have a lower upper bound: trulens-providers-cortex and trulens-connectors-snowflake install on Python 3.10 through 3.13, and the deprecated trulens-apps-nemo installs on Python 3.10 through 3.12 only.

These installation instructions assume that you have conda installed and added to your path.

1. Create a virtual environment (or modify an existing one).

   conda create -n "<my_name>" python=3  # Skip if using existing environment.
   conda activate <my_name>
   

2. [Pip installation] Install the trulens pip package from PyPI.

   pip install trulens
   

3. [Local installation] If you would like to develop or modify TruLens, you can download the source code by cloning the TruLens repo.

   git clone https://github.com/truera/trulens.git
   

4. [Local installation] Install the TruLens repo.
