Error when implementing probabilistic augmentations

Describe the question.

I have tested with DALI 1.38 and DALI 1.39 on CUDA 12.2

I am trying to specify configurations for various augmentation operations in a hydra configuration file and then I want to construct those augmentations inside a pipeline. For instance, following is an example of a configuration file for random_horizontal_flip

The corresponding implementation is as below :

In a similar fashion I have configurations for other augmentations as well.

In my main code, I construct a pipeline as follows ( explanation follows )

So, as you can see following is the sequence of operations

1. You pass a set of hydra configuration files to a class MyDataset .
2. The corresponding functions are then built as partial functions using hydra.utils.instantiate
3. Then they are used for augmentation inside the pipeline using self._transform_data(....)

I have chosen this mechanism as it allows me to choose and modify all aspects of data augmentation using Hydra.

However, when running I often get error messages which tend to suggest that something is wrong with dali_fn.random.uniform(...) because whenever I use two augmentations ( e.g :- resize_exact and horizontal_flip ) it will always give me weird errors which will disappear when :

a) Either I don't use any random.uniform function

b) Or I use only one augmentation

what is going wrong in my implementation ? Any hints ? Shouldn't NVIDIA DALI consider random.uniform nodes defined in different functions as different nodes ?
