A keras implementation of ENet (abandoned for the foreseeable future)

Overview

ENet-keras

license Read the Docs

This is an implementation of ENet: A Deep Neural Network Architecture for Real-Time Semantic Segmentation, ported from ENet-training (lua-torch) to keras.

Installation

Get code

git clone https://github.com/PavlosMelissinos/enet-keras.git
cd enet-keras

Setup environment

Dependencies

On poetry: poetry install

On Anaconda/miniconda: conda env create -f environment.yml

On pip: pip install -r requirements.txt

Set up data/model

make setup

The setup script only sets up some directories and converts the model to an appropriate format.

Usage

Train on MS-COCO

make train

Remaining tasks

  • Clean up code
    • Remove hardcoded paths
    • Add documentation everywhere
  • Test code
    • Add tests
  • Fix performance (mostly preprocessing bottleneck)
    • Remove unnecessary computations in data preprocessing
    • Index dataset category internals. Dataset categories have fields with one-to-one correspondence like id, category_id, palette, categories. This seems like perfect table structure. Might be too much though.
    • (Optionally) Make data loader multithreaded (no idea how to approach this one, multithreadedness is handled by keras though)
  • Enhance reproducibility/usability
    • Upload pretrained model
    • Finalize predict.py
      • Test whether it works after latest changes
      • Modify predict.py to load a single image or from a file. There's no point in loading images from the validation set.
  • Fix bugs
    • Investigate reason for bad results, see #11
    • Fix MSCOCOReduced, also see #9
    • ?????

  • Output shows no segmentation on a test image

    Output shows no segmentation on a test image

    I have the following function get_model() which returns the enet model with weights loaded from torch_enet.pkl. The functions build() and transfer_weights() are from src/test.py.

    def get_model(num_class):
        nc = num_class    # number of classes
        dw = 256
        dh = 256
    
        autoencoder, model_name = build(nc=nc, w=dw, h=dh)
    
        weights_fname = "trained_segmenter_weights.hdf5"
    
        if os.path.exists(weights_fname):
            autoencoder.load_weights(weights_fname)
        else:
            autoencoder = transfer_weights(model=autoencoder)
            autoencoder.save_weights(weights_fname)
    
        return autoencoder
    
    

    I created a model with 11 classes by calling get_model(11). I fed the image 2015-11-08T13.52.54.655-0000011482.jpg from SUNRGBD dataset. The model gave a prediction tensor which I reshaped to (256, 256, 11). To visualize the predictions, I used the following function to save that tensor as an image:

    def save_output(pred):
        h, w , nc = pred.shape
        print(h, w, nc)  # Prints: 256 256 11
    
        colors = [(random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
                  for i in range(nc)
                 ]
        output = np.zeros((h, w, 3))
    
        for i in range(h):
            for j in range(w):
                vals = pred[i, j, :].ravel().tolist()
                pos = vals.index(max(vals))
                output[i, j] = colors[pos]
    
        out_f = "pred_output.jpg"
        ret = cv2.imwrite(out_f, output)
    
    

    The output shows almost random assignment of colors and there's no visible segmentation at all.

    The input and the corresponding segmented output can be found below: 2015-11-08t13 52 54 655-0000011482 out_2015-11-08t13 52 54 655-0000011482

  • OpenCV dependency removal

    OpenCV dependency removal

    I'm interested in throwing away every import cv2 line because OpenCV has mostly been a pain for no reason. The attempt can be seen in the no_opencv branch

    The strongest contenders are pillow and scikit-image.

    I will be documenting my experiences here mostly as notes to myself and possibly to fuel a discussion.

    | Library | Wraps NumPy | channel order | dimension order | |-----------|----------------|---------------|------------------| | OpenCV | yes | bgr | (width, height) | | Pillow | no | rgb | (width, height) | | skimage | yes | rgb | (height, width) |

    Any suggestions are welcome!

  • usage

    usage

    It seems the coco script requires files that don't exist in the repository and for which there are no generators?

    in load_data():

         img_txt = os.path.join(data_dir, data_type, 'images.txt')
        lbl_txt = os.path.join(data_dir, data_type, 'labels.txt')
    

    Also, note that if the class values are serialized into a single image then data will be lost, categorical classes are most appropriate since a single image can be multiple classes.

  • Fix dependencies

    Fix dependencies

    Pip throws and error on the line containing: gsutil=4.46 which seems to be a typo in requirements.txt . The same issue appears in environment.yml when using conda to install the dependencies. Other than that, many of these dependencies seem to be on out-dated versions. Is there any other recommended way to get the installation to work with more recent packages?

    Hi, when I run the predict.py and train.sh, it said that can't find "enet_unpooling_best.h5 " and "pretrained/torch_enet.pkl". And I can't find the two files in the folder either. So what's wrong with it? Thanks!

  • Speed up inference

    Speed up inference

    I'm back again. I have some pretty decent results on the Camvid dataset now thanks to your help. I have a question for you, that you might be able to anwer. I'm not able to reproduce the fast inference time. In the article they state that:

    "For inference we merge batch normalization and dropout layers into the convolutional filters, to speed up all networks."

    Do you know where I can find any related litterature on how to do so or perhabs you know how they do it?

  • How to save checkpoint during training?

    How to save checkpoint during training?

    Thanks for sharing code!

    When I run train.py, I found it took a lot of time. I interrupted it during training and found there was not a checkpoint has been saved. I noticed that there is a callbacks() function in the train.py. I guess this is used for saving checkpoint. But I didn't see it was called during training. So how could I save the checkpoint during training periodically? For example, I want to save the checkpoint after trained every 1000 images.

    Looking forward to your response. Thank you so much. @PavlosMelissinos

  • End-to-end training

    End-to-end training

    I see you are training the model end-to-end style, while, in the original paper, they train the encoder first in order to categorize downsampled regions and then they append the decoder afterwards. What are you thoughts on this? Do you have any intuition why it might be better to train it encoder-decoder style rather than end-to-end?

    • Fix a regular expression DoS vulnerability in the py.path.svnwc SVN blame functionality (CVE-2020-29651)
    • Update vendored apipkg: 1.4 => 1.5
    • Update vendored iniconfig: 1.0.0 => 1.1.1

    • Add type annotation stubs for the following modules:

      • py.error
      • py.iniconfig
      • py.path (not including SVN paths)
      • py.io
      • py.xml

      There are no plans to type other modules at this time.

      The type annotations are provided in external .pyi files, not inline in the code, and may therefore contain small errors or omissions. If you use py in conjunction with a type checker, and encounter any type errors you believe should be accepted, please report it in an issue.

    1.8.2 (2020-06-15)

    • On Windows, py.path.locals which differ only in case now have the same Python hash value. Previously, such paths were considered equal but had different hashes, which is not allowed and breaks the assumptions made by dicts, sets and other users of hashes.
