# Tf 2.5 in a virtualenv on ubuntu 20.04

May 19, 2021

1. Install Lambda stack  
2. Create virtualenv, e.g. `pyenv virtualenv 3.9.5 common`  
3. `pip install tensorflow`

And then:

```bash
echo ‘/usr/lib/python3/dist-packages/tensorflow’ | sudo tee /etc/ld.so.conf.d/tensorflow.conf
sudo ldconfig
```

Hope this helps somebody!
