Resnet50 implementation Problem

[servercalap]

Hi,
My own dataset for used Resnet50 backbone model. But run train.py by implementation error:
File "/Users/servercalap/tf-retinanet-master/tf_retinanet/bin/../../tf_retinanet/utils/init.py", line 20, in import_package
raise Exception(name + ' is not present in ' + package_type) from e
Exception: tf_retinanet_backbones is not present in tf_retinanet_backbones

Thank you , helping me.

Read through Readme and install the backbone first https://github.com/fizyr/tf-retinanet-backbones-resnet

Hi,
I get the same error, installing the backbone first didn't solve the problem ...
I am running on colab, here's what I did so far according to the resnet-backbone README and what @Jakedismo said :

!cd tf-retinanet-backbones-resnet-master/
!python setup.py install --user
!cd ..

then
!cd tf-retinanet
!python setup.py install --user
!cd ..

and finally running train.py with the config file given in conf folder :
!python tf_retinanet/bin/train.py --config conf/train.yaml.complete

and I get :

File "tf_retinanet/bin/../../tf_retinanet/utils/__init__.py", line 20, in import_package
  raise Exception(name + ' is not present in ' + package_type) from e
Exception: resnet is not present in tf_retinanet_backbones

Thank you for helping me
