hi i am making a model for training a datasets but at my resnet_model I am stuck at Attribute error so please help me to solving this error. do the code are here below:
from Lib.data_loader import DataLoader
from Lib.resnet_model import Resnet3DBuilder
from Lib.HistoryGraph import HistoryGraph
import Lib.image as img
from Lib.utils import mkdirs
#import tensorflow as tf
import os
from math import ceil
from keras.optimizers import SGD
#from tensorflow.keras.optimizers import SGD
from keras.callbacks import ModelCheckpoint
#from tensorflow.keras.callbacks import ModelCheckpoint
target_size = (64,96)
nb_frames = 16 # here this will get number of pictres from datasets folder
skip = 1 # using resnet we skip different layers
nb_classes = 27
batch_size = 64
input_shape = (nb_frames,) + target_size + (3,)
workers = 8
use_multiprocessing = False
max_queue_size = 20
resnet_model = Resnet3DBuilder.build_resnet_101(input_shape, nb_classes, drop_rate = 0.5)
optimizer = SGD(lr=0.01, momentum=0.9, decay=0.0001, nesterov=False)
resnet_model.compile(optimizer = optimizer, loss= "categorical_crossentropy" , metrics=["accuracy"])
model_file = os.path.join(path_model, 'resnetmodel.hdf5')
model_checkpointer = ModelCheckpoint(model_file, monitor='val_acc',verbose=1, save_best_only=True, mode='max')
history_graph = HistoryGraph(model_path_name = os.path.join(path_model, "graphs"))
nb_sample_train = data.train_df["video_id"].size
nb_sample_val = data.val_df["video_id"].size
All upper code is working fine. and the error is here:

AttributeError: 'KerasTensor' object has no attribute '_keras_shape'
so please help me to solving this errors i am unable to understand it even i am upgrade its libries.
attribute _keras_shape
is not present in tensor flow > 2.0. either upgrade your lib so it's compatible with > 2.0 or set up a virtual env to support it.
small program to test with
import tensorflow as tf
from keras.layers import Input
s = Input(shape=[1], dtype=tf.float32, name='1')
print("shape of s is: ",s._keras_shape) # (None, 1)
in tf.__version__
'2.3.1' this does not work and throws AttributeError: 'Tensor' object has no attribute '_keras_shape'
the workaround, if you still not ready for 2.0
create a virtual env: tensor1
virtualenv -p 2.7 tensor1
install older version on tensor and keras
pip install tensorflow==1.15
pip install keras==2.2.4
and then hopefully this particular error will go away, but you might land up with new errros.
