# Running Jax with cudnn provided by lambda-stack

## post by simonsays on Feb 21, 2022

I am trying to install [jax](https://github.com/google/jax) on a lambda machine which has the lambda-stack installed but I am unable to locate cudnn and make it visible to my jax installation.

Where should libcudnn be located if the stack was correctly installed? Is there a recommended way of install jax with the lambda stack?

Thanks,

Simon

you should find it under:

/usr/lib/python3/dist-packages/tensorflow/

make sure to add the path to LD_LIBRARY_PATH variable which is for runtime and LIBRARY_PATH variable for compile time linking in your bash profile or bashrc file.
