Any idea of this problem? Thank you very much.

Hello,I have a question.Where is the "caffe_layers_value.pickle"?

I have the same issue,

[YangBain]

@my1347 add list before map, just like list(map()), you can solve your problems.

[my1347]

@YangBain already do that, but it didn't work

I know this is a few months old, but I just encountered same issue and fixed.

@my1347 did you do it for the lines before np.hstack? image_paths_per_label is a map and trying to be subscribed in the next line, so the list conversion also has to happen on the preceeding line as well.

@eanderson4 I use python3.5.4 ,modified like this: image_paths_per_label = list(map(lambda one_dir: map(lambda one_file: os.path.join( dataset_path, one_dir, one_file ), os.listdir( os.path.join( dataset_path, one_dir))), image_dir_list)) image_paths_train = np.hstack(list(map(lambda one_class: one_class[:-10], image_paths_per_label)))

it still do not work ,same problem

@lz666win In that line there are two map (which is marked bold below) , if you replace that also with list(map) it works

image_paths_per_label = list(map(lambda one_dir: map(lambda one_file: os.path.join( dataset_path, one_dir, one_file ), os.listdir( os.path.join( dataset_path, one_dir))), image_dir_list))
