Placeholder issue

[bakirillov]

When I run as follows: python inference/image_translation_infer.py --model_path="\~/Documents/weights/256" --image_hw=256 --input_tensor_name="sources_ph" --output_tensor_name="custom_generated_t_style_source:0" input_image_path="\~/Documents/art/photo.jpg" --output_image_path="\~/Documents/art/" --num_output=1 I get that error: Traceback (most recent call last): File "/home/bakirillov/anaconda3/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 1278, in _do_call return fn(*args) File "/home/bakirillov/anaconda3/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 1263, in _run_fn options, feed_dict, fetch_list, target_list, run_metadata) File "/home/bakirillov/anaconda3/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 1350, in _call_tf_sessionrun run_metadata) tensorflow.python.framework.errors_impl.InvalidArgumentError: You must feed a value for placeholder tensor 'Placeholder' with dtype uint8 and shape [?,?,?] [[Node: Placeholder = Placeholder[dtype=DT_UINT8, shape=[?,?,?], _device="/job:localhost/replica:0/task:0/device:GPU:0"]()]] [[Node: custom_generated_t_style_source/_2051 = _Recv[client_terminated=false, recv_device="/job:localhost/replica:0/task:0/device:CPU:0", send_device="/job:localhost/replica:0/task:0/device:GPU:0", send_device_incarnation=1, tensor_name="edge_1565_custom_generated_t_style_source", tensor_type=DT_FLOAT, _device="/job:localhost/replica:0/task:0/device:CPU:0"]()]]

During handling of the above exception, another exception occurred:

What am I doing wrong? Python 3.6.4. Anaconda, tensorflow 1.10, keras 2.2.2

Sorry for the late reply. You seem to be missing a -- for the input_image_path flag. (Happens to me all the time)

Please try

python inference/image_translation_infer.py --model_path="~/Documents/weights/256" --image_hw=256 --input_tensor_name="sources_ph" --output_tensor_name="custom_generated_t_style_source:0" --input_image_path="~/Documents/art/photo.jpg" --output_image_path="~/Documents/art/" --num_output=1

Thanks!

Thank you very much! Now it works!
