Try to remove multiprocessing and debug

Changed the code , got the same error

kbrodt · 2021-12-10T17:42:59Z

It's a problem of tensorflow. Are data and features_description in parsed = tf.io.parse_single_example(data, features_description) correct?

karanveersingh5623 · 2021-12-11T07:30:10Z

Thanks for reply
I just used one tf record with above code , it also failed . So data looks fine
Coming to features description , its defined in the script , so I couldn't figure out .
What else I can try ?

features_description = {}
features_description.update(roadgraph_features)
features_description.update(state_features)
features_description.update(traffic_light_features)

kbrodt · 2021-12-12T04:50:36Z

I've tested on my machine and there were no errors.

The tensorflow version:

tensorflow==2.5.0
tensorflow-addons==0.10.0
tensorflow-estimator==1.13.0
tensorflow-gpu==2.0.0

karanveersingh5623 · 2021-12-13T05:03:26Z

Same Error , below are the versions information . I am using Tensorflow 2.5.0 GPU docker image .

if you have any docker image , can you share ?

kbrodt · 2021-12-13T05:37:25Z

Did you try with another samples or redownload new uncompressed/tf_example/{training,validation,testing}?

No docker.

karanveersingh5623 · 2021-12-13T12:13:46Z

yea , I thought the same ….. so downloaded just 2 TF records again and tried …..same error .
Reading TF records runs fine but when the time comes to write the records , there it fails...…..
Don't know how can I proceed
