Installation notes

MLwP is built using Python 3.5. The easiest way to set up a compatibleenvironment is to useConda. This will set up a virtualenvironment with the exact version of Python used for development along with all thedependencies needed to run MLwP.

  1. Download and install Conda.
  2. Create a Conda environment with Python 3.

(Note: entercd ~ 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

The environment is successfully created.

  1. Now activate the Conda environment.

    source activate *your env name*

    You will get the following

    (mlwp-test) amogh@hp15X34:~$

    Enterconda list to get the list of available packages

        (mlwp-test) amogh@hp15X34:~$ conda list# packages in environment at /home/amogh/anaconda3/envs/mlwp-test:## Name                    Version                   Build  Channelca-certificates           2018.12.5                     0  certifi                   2018.8.24                py35_1  libedit                   3.1.20181209         hc058e9b_0  libffi                    3.2.1                hd88cf55_4  libgcc-ng                 8.2.0                hdf63c60_1  libstdcxx-ng              8.2.0                hdf63c60_1  ncurses                   6.1                  he6710b0_1  openssl                   1.0.2p               h14c3975_0  pip                       10.0.1                   py35_0  python                    3.5.6                hc3d631a_0  readline                  7.0                  h7b6447c_5  setuptools                40.2.0                   py35_0  sqlite                    3.26.0               h7b6447c_0  tk                        8.6.8                hbc83047_0  wheel                     0.31.1                   py35_0  xz                        5.2.4                h14c3975_4  zlib                      1.2.11               h7b6447c_3
  2. Install the required dependencies.

    (mlwp-test) amogh@hp15X34:~$ conda install --yes --file *path to requirements.txt*
  3. In case you are not able to install the packages or gettingPackagesNotFoundErrorUse the following command conda install -c conda-forge *list of packages separated by space*. For more info, refer issue#3Unable 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)

Issues

Feel free to submit issues and enhancement requests.

Contributing

Please refer to each project's style guidelines and guidelines for submitting patches and additions. In general, we follow the "fork-and-pull" Git workflow.

  1. Fork the repo on GitHub
  2. Clone the project to your own machine
  3. Commit changes to your own branch
  4. Push your work back up to your fork
  5. Submit aPull request so that we can review your changes
