TypeError: None has type NoneType, but expected one of: int, long #2

jtara1 · 2017-08-01T18:00:55Z

I have 23 images I'm testing this out with. I labeled my images with the bounding boxes using labelimg. I cloned this repo and updated the contents of the images, annotations, data, and training folders to hold the data I'm using. I ran the xml_to_csv.py script.
I ran the generate_tfrecord.py script and got this error.

j@j-pc ~/_Github-Projects/raccoon-dataset $ python3 generate_tfrecord.py --csv_input=./data/raccoon_labels.csv --output_path=train.record

Changing the string in https://github.com/datitran/raccoon-dataset/blob/master/generate_tfrecord.py#L25 to the label I'm using ('iron ore') for my data seems to have fixed this. No errors now and I got the train.record file. I'll probably close this issue later after I make sure this file is legit.

Zumbalamambo · 2017-08-31T20:49:42Z

@jtara1 what do you mean by iron ore?

jtara1 · 2017-08-31T21:47:30Z

'iron ore' is the label I assigned. It describes what I'm training the model to detect, that is, iron ore, an object from an online game.

Whatever your label is, it should match what's located in https://github.com/datitran/raccoon_dataset/blob/master/training/object-detection.pbtxt

(raw text):

item {
  id: 1
  name: 'raccoon'
}

my previous comment points to the wrong line number; at that time I needed to replace the string 'raccoon' in the func below of the same file with 'iron ore' b/c that was my label

# TO-DO replace this with label map
def class_text_to_int(row_label):
    if row_label == 'raccoon':
        return 1
    else:
        None

It's been a while since I touched this stuff, mb if I misstated something.

shauviks · 2018-10-11T11:40:19Z

Can some one help me on this. Even i changed return value to 0 but i still get the same error

prameshbajra · 2019-02-07T09:00:47Z

@shauviks can you post your error trace? or did you solve it?

This should return an integer in the else case,since line number 87 "'image/object/class/label': dataset_util.int64_list_feature(classes)," expects it to be an integer, returning an integer like 0 worked for me.

pranavjadhav001 · 2019-06-25T11:11:24Z

This happens because labels in your xml are wrong in someplaces, check your csv and change those mistakes. Like instead of racoon label , you have labelled it as car.

jayasuryar97 · 2019-10-09T12:00:22Z

My object-detection.pbtxt
item { id: 1 name: 'PAN' } item { id: 2 name: 'Cheque' } item { id: 3 name: 'Unknown' }
It has multiple classes.
How do i modify my class_text_to_int function for multi class

nuttheguitar · 2019-11-12T09:57:06Z

python generate_tfrecord.py --label=person --csv_input=../../annotations/train_labels.csv --output_path=../../annotations/train_labels.record --img_path=../../images/train

This is my run script. I just change '--label' to match with a class that you assigned in label_map.txt

adarsh666 · 2019-12-21T11:26:03Z

This usually happens when "label name" specified to create the tf record mismatches with the "label name" in the annotation files.
For example if u annotated an image by the name "cars" , and u incorrectly named label as "car" while creating tf record.

SirPhemmiey · 2020-01-07T06:35:02Z

The solution is a simple one.

You just need to change the else statement so it returns 0 instead of "None".

def class_text_to_int(row_label): if row_label == '<YOUR LABEL NAME>': return 1 else: return 0

You can find def class_text_to_int in the generate_tfrecord.py file.

Most forums talk about return equal None. It should be zero.

Ref: here

I hope it works for you!

It is working great.
Thank you.
Simply do the thing in the image.

It still doesn't work!

IndiskPrasad · 2020-04-26T11:14:11Z

@yashmukaty , it worked for me by simply adding 0 instead of None. thanks

bahshat · 2020-05-15T12:59:27Z

You need this piece

def class_text_to_int(row_label):
    if row_label == '<YOUR LABEL NAME>': 
         return 1 
    else: 
         return 0

You can find def class_text_to_int in the generate_tfrecord.py file.
find the else shown in the above code
there you'd see

else: 
         None

make as above code which needs to be replaced with

  else: 
         return 0

dhanpalrajpurohit · 2020-05-20T13:24:16Z

if row_label == 'raccon': return 1 else: None
convert to
if row_label == 'raccon': return 1 else: return 0

TO-DO replace this with label map

if row_label == 'raccoon':
return 1
else:
None

This should return an integer in the else case,since line number 87 "'image/object/class/label': dataset_util.int64_list_feature(classes)," expects it to be an integer, returning an integer like 0 worked for me.

This function only makes sense if you want to filter your label in csv with many labels but the code isn't checking for None so it doesn't have purpose.
Just comment out the whole thing and return 1 always

Below is what I did and it works for all labels I have in my csv:

TO-DO replace this with label map

def class_text_to_int(row_label):
# print(row_label + " ")
# if row_label == 'car' or row_label == 'plate'
# or row_label == 'motorcycle' or row_label == 'bus'
# or row_label == 'volkwagen' or row_label == 'chevrolet'
# or row_label == 'truck' or row_label == 'van' or row_label == 'suv':
# return 1
# else:
# None
return 1

Thanks for the help :)

Just change the label name whatever you labeling them during crop the image by labelImg tool.

def class_text_to_int(row_label):
    if row_label == 'raccon':
        return 1
    else:
        None

Instead of 'raccon' put label name for ex:- 'car'.

NOTE:- for windows just change the forward-slash like:-
python3 generate_tfrecord.py --csv_input=data\test_labels.csv --output_path=data\test.record
