CBNA

To run our code you need to go through the following steps:.
Start a fresh conda environment and install the necessary packages. We have provided an environment.yml with our used environment.
Create a dataset folder where all the used datasets will be stored. Specify the environment variables UBNA_DIR_DATASET and UBNA_DIR_CHECKPOINT, leading to the paths of this dataset folder and the folder where the checkpoints are to be saved. Depending on your operating system, this can be done as follows: Windows: setx UBNA_DIR_DATASET <PATH_TO_DATASET> Linux: export UBNA_DIR_DATASET=<PATH_TO_DATASET>
To download the datasets, you can use the following steps. Note that you do not necessarily need all datasets for all experiments (e.g. for GTA to Cityscapes you only need gta-5 and Cityscapes and Cityscapes sequence datasets), but if you download all datasets mentioned here, you should be able to run all experiments described in the paper: Cityscapes: Create a folder called cityscapes in your dataset folder. Go to https://www.cityscapes-dataset.com/downloads/, log in, download and unpack the following dataset parts into that folder: leftImg8bit_trainvaltest.zip gtFine_trainvaltest.zip Cityscapes (sequences): Create a folder called cityscapes_sequence in your dataset folder. Go to https://www.cityscapes-dataset.com/downloads/, log in, download and unpack the following dataset parts into that folder: leftImg8bit_sequence_trainvaltest.zip GTA-5: Download all parts of the GTA-5 dataset from https://download.visinf.tu-darmstadt.de/data/from_games/. Put all color images in a subfolder images and all labels in a subfolder labels. Rename the main folder to gta5 afterwards. GTA-5 (full split): Create an empty folder called gta5_full_split. It will be used later to store the split information for the GTA-5 dataset.
Download the .json files from the following download links and place them in the dataset folders. Cityscapes: https://drive.google.com/drive/folders/1E9RdGX-uAtrU1p_OLjOrVI4tKBdZwg6W?usp=sharing Cityscapes (sequences): https://drive.google.com/drive/folders/1EKGfzjotMc8_R42nHaMmwIfyyv0W4Q42?usp=sharing GTA-5: https://drive.google.com/drive/folders/1uv4iaOiJ0fbZOHcrTcmFLqje5WdXazPR?usp=sharing GTA-5 (full split): https://drive.google.com/drive/folders/18t4Alb8jhk8Y7BqbxAAK9k8-Yqx1wxBE?usp=sharing The resulting folder structure should look as follows. . ├── cityscapes │ ├── gtFine │ ├── leftImg8bit │ ├── basic_files.json │ ├── parameters.json │ ├── train.json │ ├── validation.json │ └── test.json │ ├── cityscapes_sequence │ ├── leftImg8bit_sequence │ ├── basic_files.json │ ├── parameters.json │ ├── train.json │ ├── validation.json │ └── test.json │ ├── gta5 │ ├── images │ ├── labels │ ├── basic_files.json │ └── parameters.json │ |── gta5_full_split | └── train.json
