Hi there, there is an error at: http://localhost:8080/notebooks/classification/examples.ipynb
pls refer the details:

preparing input and output dictionaries

creation of output dictionary

output_dict = {"softmax_tensor:0": graph.get_tensor_by_name("softmax_tensor:0")}

initialization of ImageNet dataset

​

creation of output dictionary

output_dict = {"softmax_tensor:0": graph.get_tensor_by_name("softmax_tensor:0")}
​

initialization of ImageNet dataset

imagenet = ImageNet(
batch_size=LAT_BATCH_SIZE,
color_model="RGB",
pre_processing="VGG",
is1001classes=True
)
​
input_array = imagenet.get_input_array(target_shape=input_shape)
​

assignment of input image to input tensor

feed_dict = {graph.get_tensor_by_name("input_tensor:0"): input_array}
​

for the purpose of visualizing results let's load the image without pre-processing

img = cv2.imread(str(imagenet.path_to_latest_image))
ERROR:root:Internal Python error in the inspect module.
Below is the traceback from this internal error.
