Prerequisite

In order to run the code, your setup has to meet the following minimum requirements (tested versions in parentheses. Other versions might work, too):

• Python 3.5 (3.5)
  • Chianti https://github.com/TobyPDE/chianti
  • Theano (0.9.0.dev1) with cuDNN (5004)
  • Lasagne (0.2.dev1)
  • OpenCV (3.1.0)
  • Scikit-Learn (0.17.1)
  • Numpy (1.11.0)

How do I evaluate the pre-trained model?

Step by step guide:

1. Download and extract the files gtFine_trainvaltest.zip and leftImg8bit_trainvaltest.zip (11GB) from the CityScapes website.
2. Clone the repository
3. Change into the FRRN directory and run $ python predict_frrn_[a|b].py
4. When being asked, enter the path to the directory where you extracted the dataset to and choose the default model file.

How do I train a new model?

Step by step guide:

1. Download and extract the files gtFine_trainvaltest.zip and leftImg8bit_trainvaltest.zip (11GB) from the CityScapes website.
2. Clone the repository
3. Inspect the configuration at the beginning of the file train_frrn_[a|b].py and change it if necessary.
4. Run $ python train_frrn_[a|b].py
5. When being asked, enter the path to the directory where you extracted the dataset to and choose a new model file and new log file.

How do I monitor training?

Simply run $ python log_monitor.py [your log file].
