Python 3.9 is very new and it may not be working with your system try switching back to python 3.8.6 and it looks like you havent added python to path

I had the same problem and I was trying to open (pythonw.exe)
it turns out that I had to open Python\Lib\idlelib\idle.py type(python file(no console))

Python Behave BDD Tutorial Error on Windows

So, I`m comparing some python test frameworks and came across behave. Thought it was interesting and worth a test drive.
Followed the steps on the tutorial, available at:
https://behave.readthedocs.io/en/stable/tutorial.html
When I ran the behave command on Powershell (Win10 and Python 2.7.10), I got the following error:
Exception TypeError: compile() expected string without null bytes

Has anyone encountered this error while trying to run behave? (Found some threads online related mainly to flask issues but I couldn't solve the problem)

Answering my own question here.
It was an encoding problem.
Sublime was saving my files with an encoding different from UTF-8.
File -> Save with Encoding -> UTF-8 did the trick.

tensorflow.python.framework.errors_impl.NotFoundError: data/kitti_label_map.pbtxt; No such file or directory

I'm trying to convert the kitti dataset into the tensorflow .record. After I typed the command:
python object_detection/dataset_tools/create_kitti_tf_record.py
--lable_map_path=object_detection/data/kitti_label_map.pbtxt --data_dir=/Users/zhenglyu/Graduate/research/DataSet/kitti/data_object_image_2/testing/image_2
--output_path=/Users/zhenglyu/Graduate/research/DataSet/kitti2tf/train.record
validation_set_size=1000
I got this error:

c_api.TF_GetCode(self.status.status)) tensorflow.python.framework.errors_impl.NotFoundError:
data/kitti_label_map.pbtxt; No such file or directory
The file exists for sure. And I don't know why as I set the label_map_path to another one (object_detection/data/kitti_label_map.pbtxt), the path still remains the default setting (data/kitti_label_map.pbtxt).
I know there's a lot of related problem but none of the solutions that I found works for me. I used Virtualenv to install the tensorflow and using python 3.6. Could these be the problem? Thanks!

I don't have a definitive solution to this but here is what resolved it.
First, I copied the kitti_label_map.pbtxt into the data_dir. Then I also copied create_kitti_tf_record.py into the data_dir. And now I copied(this is what made it run in the end) the name and absolute path of the kitti_label_map.pbtxt and pasted it as label_map_path
I have no idea why but it worked.

Error exporting inference graph (ValueError)

So I'm following sentdex's object detection tutorial and I have gotten to the step where you are supposed to export the inference graph. I'm using the "export_inference_graph.py" script from Tensorflow's object_detection folder.
The problem is that I'm getting this ValueError:
Traceback (most recent call last):
File "C:\Users\Zelcore-Dator\AppData\Local\Programs\Python\Python35\lib\site-packages\google\proto
buf\internal\python_message.py", line 545, in _GetFieldByName

KeyError: 'layout_optimizer'
During handling of the above exception, another exception occurred:

ValueError: Protocol message RewriterConfig has no "layout_optimizer" field.
I'm guessing that it has something to do with protobuf, but I've reinstalled it several times already with no success.
All help appreciated

Happened to me too. Didn't happen few weeks ago.
Until the bug is fixed, you could use an earlier version that still works.
replace line 72 in 'object_detection/exporter.py':
layout_optimizer=rewriter_config_pb2.RewriterConfig.ON)
with the old and working line:
optimize_tensor_layout=True)

I used:
rewrite_options = rewriter_config_pb2.RewriterConfig(optimize_tensor_layout=True)
but kept running into the same issue UNTIL I went and reran
python setup.py install
from my "research" folder. Then I was able to get everything to work.

Remove optimize_tensor_layout=rewriter_config_pb2.RewriterConfig.ON
change the line 71 in exporter.py
rewrite_options = rewriter_config_pb2.RewriterConfig(optimize_tensor_layout=rewriter_config_pb2.RewriterConfig.ON)
to:
rewrite_options = rewriter_config_pb2.RewriterConfig()

I get the following error/traceback:

If anyone could point me in the right direction that would be great.
Thanks

Problem resolved.
I found the following support request on SourceForge which refers to a need to use short format (8.3) path and filenames in pychecker.bat and not long format as is allowed in newer versions of Windows.
