Error by running Demos > FileNotFoundError:liblietorch.so

[My-Corner]

Thanks for your great work. I have downloaded the model and I have faced an issue in running demos. when I run the first command "python demo.py --imagedir=data/abandonedfactory --calib=calib/tartan.txt --stride=2" I get an error "FileNotFoundError: Error: Could not find /home/cdh-h91/anaconda3/lib/python3.9/site-packages/lietorch/lib/liblietorch.so" I could not find liblietorch.so anywhere, I have installed lietorch... Any help would be appreciated!

Getting this error...plz help me out

To save the reconstruction with full resolution depth maps use the --reconstruction_path flag.

where and how to use this

Global BA Iteration #1
Global BA Iteration #2

above things are done using environment_novis.yaml

by executing one demo file getting above thing.....
following things making confusion

1. what Global BA iterations stand for.......what is us of it .
2. what to do next......does the demo code helps for creation of VDO only on base of images .....
3. How can we get the 3D object from the given vdo...
4. What next step should be there
   KIndly guide and help

parser.add_argument("--reconstruction_path", help="path to saved reconstruction")
in what format should i mention the path, do have to specify its name with extension and if yes then what extension should be

I guess you should consult at lietorch oringin repo and follow their instructions on installation. However, I cannot successfully install it since it seems to need CUDA 10.2 to compile, but it is not supported by my system (Ubuntu 20.04)

[lin-fangzhou]

/home/cdh- h91/anaconda3/lib/python3.9/site-packages/lietorch/lib/liblietorch.so

really good suggestion

[Rosa712]

you can use pip install git+https://github.com/princeton-vl/lietorch.git
when I install it, error occurred.

[rashikshrestha]

I was able to solve this by building lietorch from source following instructions here
