Some questions

[theTibi]

Hi,

It's an awesome project thanks for this, I tried to reproduce it and do the same in my city, but the manual is not that detailed and sometimes it is confusing. In the last few days I tried to make it work but I couldn't based on the read.me so I would have a few questions.

I am able to do the first three steps, and the test is fine:

python object_detection/builders/model_builder_test.py
.............
----------------------------------------------------------------------
Ran 13 tests in 0.066s

OK

Then we have to run the following:

./generate_tfrecord --folder=path/to/data_dir --train_ratio=.70

I suppose the path/to/data_dir int this example is OurCamera/data/ folder.
It gives an error, I am still trying to figure out why, maybe I am doing something wrong but it looks like it gets str type instead of bytes:

(data) root@mlearning:~/data# python ./generate_tfrecord.py -folder=/root/data/data/ -train_ratio=.70
Running on /root/data/data/ with ratio 0.7

    return tf.train.Feature(bytes_list=tf.train.BytesList(value=[value]))

You write unzip Unzip model in the data/models/ folder , in that case the the data structure should look like this:

data/test.record data/train.record data/models/model/faster_rcnn_resnet101_coco_11_06_2017 data/models/model/train data/models/model/eval

Am I right?

I am still trying to make it work, but if you have any comments I would appreciate it..

Sorry didnt see this till now. Turning on notifications for this repo so I should see future messages.

1. For your question about unzipping the model in the data/models/ folder yes your structure looks correct.

2. Hmmm, I cant replicate the issue of line 82 of generate_tfrecord. What version of the tensorflow research are you using?

Hi,

I am using Python3.5 on Ubuntu. I installed tensorflow with following command:

pip3 install --upgrade tensorflow

And the version what it is installed is: tensorflow (1.6.0)

Thanks.

Some other people has said that the problem came from : and spaces in the filenames for the images. You can try renaming all the files to remove the : and the " "

I dont have that problem on my system, but let me know if that solved your problem. If it did than I will have to find some way of replicating and fixing.
