Description: # pad-sequences
        Pad variable length sequences with multiples features.
        
        ## Installation via pip
        The `pad-sequences` [git repo](http://github.com/ulf1/pad-sequences) 
        is available as [PyPi package](https://pypi.org/project/pad-sequences)
        
        ```
        pip install "pad-sequences>=0.3.0"
        ```
        
        
        ## Usage
        
        ```
        from pad_sequences import pad_sequences_multi
        import tensorflow as tf
        # import torch
        
        seq = []
        seq.append([[1, 1, 1], [2, 2, 2]])
        seq.append([[1, 1, 1], [2, 2, 2], [3, 3, 3], [4, 4, 4]])
        
        n_samples = len(seq)
        n_features = len(seq[0][0])
        n_timesteps = 3
        
        # for input sequences
        padded = pad_sequences_multi(seq, padding='pre', value=0, 
                                     truncating='pre', maxlen=n_timesteps)
        
        # for output sequences
        # padded = pad_sequences_multi(seq, padding='post', value=0, 
        #                              truncating='post', maxlen=n_timesteps)
        
        
        X = tf.reshape(padded, [n_samples, n_timesteps, n_features])
        # X = torch.reshape(torch.tensor(padded), [n_samples, n_timesteps, n_features])
        ```
        
        
        Check the [examples](http://github.com/ulf1/pad-sequences/examples) folder for notebooks.
        
        
        ## Commands
        Install a virtual environment
        
        ```
        python3 -m venv .venv
        source .venv/bin/activate
        pip3 install --upgrade pip
        pip3 install -r requirements-dev.txt
        pip3 install -r requirements-demo.txt
        ```
        
        (If your git repo is stored in a folder with whitespaces, then don't use the subfolder `.venv`. Use an absolute path without whitespaces.)
        
        ## Other python commands
        
        * Jupyter for the examples: `jupyter lab`
        * Check syntax: `flake8 --ignore=F401 --exclude=$(grep -v '^#' .gitignore | xargs | sed -e 's/ /,/g')`
        * Run Unit Tests: `pytest`
        * Upload to PyPi with twine: `python setup.py sdist && twine upload -r pypi dist/*`
        
        Clean up 
        
        ```
        find . -type f -name "*.pyc" | xargs rm
        find . -type d -name "__pycache__" | xargs rm -r
        rm -r .pytest_cache
        rm -r .venv
        ```
        
        
        ## Debugging
        * Notebooks to profile python code are in the [profile](http://github.com/ulf1/pad-sequences/profile) folder
