Unknown data_format

[rifaadev]

Hi, I tried to run the ENAS project and I am blocked by this error : File "/enas-add-license-1/enas-add-license-1/src/cifar10/micro_child.py", line 258, in _model
raise ValueError("Unknown data_format '{0}'".format(self.data_format))
ValueError: Unknown data_format 'NHWC'
I would like to know if it is a problem with my environment. I use python 3.6 and tensorflow 1.13.2 or something else.
thank you a lot
