Cannot instantiate any model

[dettmar]

I cannot instantiate any RDN or RRDN model. I'm running Ubuntu 18.04, Python 3.6.6, and using the latest version of ISR (v2.2.0) which was installed using the pip install ISR command. Steps to reproduce:

>>> from ISR.models import RDN
>>> rdn = RDN(weights='psnr-small')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ubuntu/env/lib/python3.6/site-packages/ISR/models/rdn.py", line 104, in __init__
    self.model = self._build_rdn()
  File "/home/ubuntu/env/lib/python3.6/site-packages/ISR/models/rdn.py", line 206, in _build_rdn
    )(LR_input)
  File "/home/ubuntu/env/lib/python3.6/site-packages/tensorflow_core/python/keras/engine/base_layer.py", line 817, in __call__
    self._maybe_build(inputs)
  File "/home/ubuntu/env/lib/python3.6/site-packages/tensorflow_core/python/keras/engine/base_layer.py", line 2141, in _maybe_build
    self.build(input_shapes)

    raise ValueError('The channel dimension of the inputs '
ValueError: The channel dimension of the inputs should be defined. Found `None`.

Am I missing something obvious?

Could you send the output of pip freeze?

Interesting, the TF version is correct. I don't know why this happens. Under Ubuntu 19.04 if I create a new environment with conda and then install the package, everything works.

conda create -n ISR python=3.6
conda activate ISR
pip install ISR

Could you try with such settings?
