Installation notes
MLwP is built using Python 3.5. The easiest way to set up a compatible environment is to use Conda. This will set up a virtual environment with the exact version of Python used for development along with all the dependencies needed to run MLwP.
- Download and install Conda.
- Create a Conda environment with Python 3.
(Note: enter cd ~ to go on $HOME , then perform these commands)
```
conda create --name *your env name* python=3.5
```
You will get the following, mlwp-test is the env name used in this example
