"List index of out of range error " during inference ( Show up this week ) #1537

Closed syln21 closed 3 years ago

syln21 commented 3 years ago

Hello, i have been using same notebook on colab for more than 2 months with same weights and dependencies. It started to give me error this week. I didn't change anything. It suprisingly started to give me error. while loading the model. Could you please help me ?

IndexError Traceback (most recent call last)

in () 3 4 # load retinanet model ----> 5 model = models.load_model(model_path, backbone_name='resnet50') 6 model = models.convert_model(model) 7 8 frames /usr/local/lib/python3.7/dist-packages/tensorflow/python/keras/engine/functional.py in process_node(layer, node_data) 1222 add_unprocessed_node(layer, node_data) 1223 return -> 1224 inbound_node = inbound_layer._inbound_nodes[inbound_node_index] 1225 input_tensors.append( 1226 nest.flatten(inbound_node.outputs)[inbound_tensor_index]) IndexError: list index out of range

I believe this is happening because colab upgraded to tensorflow 2.5

Thanks for your reply, I tried to downgrade tensorflow with pip install tensorflow==2.3.0 but still have the same problem, Do you have any suggestion

AndreiIonut1 commented 3 years ago

The way I managed to get it to work is to install miniconda in google colab and then install tensorflow-gpu 2.4.0.

Can I have a piece of code or a link to a working colab?

I am asking for an example of a solution to the problem. I have the same problem.

mateoochoa commented 3 years ago

You should check issue #1535, All these problems have the same reason, google colab change the version of its libraries and in some of these broke the support for the RetinaNet.
