OSError while calling Detectron2LayoutModel

After successfully installing Layout Parser in Windows, getting the below OS Error.
Code Used:

Please help

Even I got a similar error. I tried out manually some work around in Windows.
I am using your case as example: OSError: [Errno 22] Invalid argument: 'C:\Users\vchinna/.torch/iopath_cache\s/nau5ut6zgthunil\config.yaml?dl=1.lock'
Please follow the following process.
Navigate to C:\Users\vchinna/.torch/iopath_cache\s/nau5ut6zgthunil\config.yaml
Open that config.yaml file
Scroll down to WEIGHTS: https://www.dropbox.com/s/h7th27jfv19rxiy/model_final.pth?dl=1 should be around 265 line.
Copy that link and paste it in your browser, a 'model_final.pth' will be downloaded. Copy this file to your desired folder.
Now replace the path to WEIGHTS: your_desired_folder/model_final.pth
Save it and run the code it works!
But there is a small work around I think before you do this (if you have not done)

Not sure why my build_image_data.py script for tensforflow isn't working

I'm trying to convert a set of jpg images to TFRecord for use with a CNN in Tensorflow.I'm using the script build_image_data.py from here:
https://github.com/tensorflow/models/blob/master/inception/inception/data/build_image_data.py
I've created a validation directory and a training directory as well as a labels.txt file with the appropriate labels. I run the script using jupyter notebook (I've also tried via command line) and I have changed the tf.app.flags.DEFINE_string arguments to the appropriate directory/file names. When I run it I get the following error:

Using Sacred Module with iPython

I am trying to set up sacred for Python and I am going through the tutorial. I was able to set up sacred using pip install sacred with no issues. I am having trouble running the basic code:
from sacred import Experiment
ex = Experiment("hello_world")
Running this code returns the a ValueError:

64
65 mainfile = get_py_file_if_possible(os.path.abspath(filename))
ValueError: invalid filename or file not found "None"
I am not sure why this error is returning. The documentation does not say anything about setting up an Experiment file prior to running the code. Any help would be greatly appreciated!

The traceback given indicates that the constructor for Experiment searches its namespace to find the file in which its defined.
Thus, to make the example work, place the example code into a file and run that file directly.
If you are using ipython, then you could always try using the %%python command, which will effectively capture the code you give it into a file before running it (in a separate python process).

According to the docs, if you're in IPython/Jupyter, you can allow the Experiment to run in a non-reproducible interactive environment:
ex = Experiment('jupyter_ex', interactive=True)
https://sacred.readthedocs.io/en/latest/experiment.html#run-the-experiment

The docs say it nicely (TL;DR: sacred checks this for you and fails in order to warn you)
Warning
By default, Sacred experiments will fail if run in an interactive
environment like a REPL or a Jupyter Notebook. This is an intended
security measure since in these environments reproducibility cannot be
ensured. If needed, this safeguard can be deactivated by passing
interactive=True to the experiment like this:
ex = Experiment('jupyter_ex', interactive=True)

Setting interactive=True doesn't work if you run the notebook as a script through ipython.
