@Sharron4me why there is no tf present in requirements file.
please mention all required packages to reproduce it.

Hi everybody, I'm trying to execute this version of keras-frcnn but I'm receiving the following error:
Traceback (most recent call last): File "keras-frcnn/train_frcnn.py", line 118, in <module> img_input = Input(shape=input_shape_img) File "C:\Users\loand\Anaconda3\envs\ex_frcnn_bloodcells\lib\site-packages\keras\engine\topology.py", line 1389, in Input input_layer = InputLayer(batch_input_shape=batch_shape, File "C:\Users\loand\Anaconda3\envs\ex_frcnn_bloodcells\lib\site-packages\keras\engine\topology.py", line 1300, in __init__ input_tensor = K.placeholder(shape=batch_input_shape, File "C:\Users\loand\Anaconda3\envs\ex_frcnn_bloodcells\lib\site-packages\keras\backend\tensorflow_backend.py", line 351, in placeholder x = tf.compat.v1.placeholder(dtype, shape=shape, name=name) File "C:\Users\loand\Anaconda3\envs\ex_frcnn_bloodcells\lib\site-packages\tensorflow\python\ops\array_ops.py", line 3023, in placeholder raise RuntimeError("tf.placeholder() is not compatible with " RuntimeError: tf.placeholder() is not compatible with eager execution.

Has anybody managed to solve it previously?

Hi @andrealoddo ,
Try doing this
tf.compat.v1.disable_eager_execution()

too many errors in the code not able to execute it
