"""
Creates a training dataset for multi-animal datasets. Labels from all the extracted frames are merged into a single .h5 file.\n
Only the videos included in the config file are used to create this dataset.\n
[OPTIONAL] Use the function 'add_new_video' at any stage of the project to add more videos to the project.
Imporant differences to standard:
- stores coordinates with numdigits as many digits
- creates
Parameter
----------
config : string
Full path of the config.yaml file as a string.
num_shuffles : int, optional
Number of shuffles of training dataset to create, i.e. [1,2,3] for num_shuffles=3. Default is set to 1.
Shuffles: list of shuffles.
Alternatively the user can also give a list of shuffles (integers!).
net_type: string
Type of networks. Currently resnet_50, resnet_101, and resnet_152, efficientnet-b0, efficientnet-b1, efficientnet-b2, efficientnet-b3,
efficientnet-b4, efficientnet-b5, and efficientnet-b6 as well as dlcrnet_ms5 are supported (not the MobileNets!).
See Lauer et al. 2021 https://www.biorxiv.org/content/10.1101/2021.04.30.442096v1
numdigits: int, optional
crop_size: tuple of int, optional
Dimensions (width, height) of the crops for data augmentation.
Default is 400x400.
crop_sampling: str, optional
Crop centers sampling method. Must be either:
"uniform" (randomly over the image),
"keypoints" (randomly over the annotated keypoints),
"density" (weighing preferentially dense regions of keypoints),
or "hybrid" (alternating randomly between "uniform" and "density").
Default is "hybrid".
paf_graph: list of lists, optional (default=None)
If not None, overwrite the default complete graph. This is useful for advanced users who
already know a good graph, or simply want to use a specific one. Note that, in that case,
the data-driven selection procedure upon model evaluation will be skipped.
trainIndices: list of lists, optional (default=None)
List of one or multiple lists containing train indexes.
A list containing two lists of training indexes will produce two splits.
testIndices: list of lists, optional (default=None)
List of one or multiple lists containing test indexes.

[OPTIONAL] Use the function 'add_new_video' at any stage of the project to add more videos to the project.
Imporant differences to standard:
- stores coordinates with numdigits as many digits
- creates
Parameter
----------
config : string
Full path of the config.yaml file as a string.
num_shuffles : int, optional
Number of shuffles of training dataset to create, i.e. [1,2,3] for num_shuffles=3. Default is set to 1.
Shuffles: list of shuffles.
Alternatively the user can also give a list of shuffles (integers!).
windows2linux: bool.
The annotation files contain path formated according to your operating system. If you label on windows
but train & evaluate on a unix system (e.g. ubunt, colab, Mac) set this variable to True to convert the paths.
net_type: string
Type of networks. Currently resnet_50, resnet_101, and resnet_152, efficientnet-b0, efficientnet-b1, efficientnet-b2, efficientnet-b3,
efficientnet-b4, efficientnet-b5, and efficientnet-b6 as well as dlcrnet_ms5 are supported (not the MobileNets!).
See Lauer et al. 2021 https://www.biorxiv.org/content/10.1101/2021.04.30.442096v1
numdigits: int, optional
paf_graph: list of lists, optional (default=None)
If not None, overwrite the default complete graph. This is useful for advanced users who
already know a good graph, or simply want to use a specific one. Note that, in that case,
the data-driven selection procedure upon model evaluation will be skipped.

"""
Creates a training dataset. Labels from all the extracted frames are merged into a single .h5 file.\n
Only the videos included in the config file are used to create this dataset.\n
[OPTIONAL] Use the function 'add_new_video' at any stage of the project to add more videos to the project.
Parameter
----------
config : string
Full path of the config.yaml file as a string.
num_shuffles : int, optional
Number of shuffles of training dataset to create, i.e. [1,2,3] for num_shuffles=3. Default is set to 1.
Shuffles: list of shuffles.
Alternatively the user can also give a list of shuffles (integers!).
windows2linux: bool.
The annotation files contain path formated according to your operating system. If you label on windows
but train & evaluate on a unix system (e.g. ubunt, colab, Mac) set this variable to True to convert the paths.
userfeedback: bool, optional
If this is set to false, then all requested train/test splits are created (no matter if they already exist). If you
want to assure that previous splits etc. are not overwritten, then set this to True and you will be asked for each split.
trainIndexes: list of lists, optional (default=None)
List of one or multiple lists containing train indexes.
A list containing two lists of training indexes will produce two splits.
testIndexes: list of lists, optional (default=None)
List of test indexes.
net_type: string
Type of networks. Currently resnet_50, resnet_101, resnet_152, mobilenet_v2_1.0,mobilenet_v2_0.75, mobilenet_v2_0.5, and mobilenet_v2_0.35 are supported.
augmenter_type: string
Type of augmenter. Currently default, imgaug, tensorpack, and deterministic are supported.

Windows:
