Versions of libraries in the requirements.txt

[xwjabc]

Hi, I would like to know if the versions of libraries in the requirements.txt can be provided. Currently I am using the latest TF (2.11) that seems to have breaking change in the optimizer. Thus, the initialization for base class in AdamWeightDecay() (https://github.com/google-research/pix2seq/blob/main/models/model_utils.py#L104) has incorrect arguments compared to the corresponding ones in https://github.com/keras-team/keras/blob/v2.11.0/keras/optimizers/optimizer_experimental/adam.py#L86. Thanks!
