Hi naokishibuya!!

Sir when i am trying to train the model for my newly created data using this command

python model.py i am getting the below error Please suggest me where i am wrong

I am using Ubuntu 16.04 and the data folder is in my home directory (containing file driving_log.csv and IMG folder) and my model.py is also in my home directory.Rest everything is working fine for pre-trained data.


Using TensorFlow backend.

Hi @DOCOPAC,

This might be due to the header row (column names) missing in the newly created driving_log.csv file.

The first line of the driving_log.csv should have the column names as follows.

center,left,right,steering,throttle,brake,speed
IMG/center_2016_12_01_13_30_48_287.jpg, IMG/left_2016_12_01_13_30_48_287.jpg, IMG/right_2016_12_01_13_30_48_287.jpg, 0, 0, 0, 22.14829
IMG/center_2016_12_01_13_30_48_404.jpg, IMG/left_2016_12_01_13_30_48_404.jpg, IMG/right_2016_12_01_13_30_48_404.jpg, 0, 0, 0, 21.87963
...

You may also want to check out the issue #2 which is probably related.

Let me know how it goes. We can continue to discuss how to solve the issue together.
