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.

  1. Download and install Conda.
  2. 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

  3. In case you are not able to install the packages or getting PackagesNotFoundError Use the following command conda install -c conda-forge *list of packages separated by space*. For more info, refer issue #3 Unable to install requirements

How good is the code ?

  • It is well tested
  • It passes style checks (PEP8 compliant)
  • It can compile in its current state (and there are relatively no issues)

How much support is available?

  • FAQs (coming soon)
  • Documentation (coming soon)
