DNS Resolution Issue with Datumaro 1.0 exported from CVAT

[Loc-Vo]

I tried to view the CVAT project state exported using "datumaro 1.0" and got the following issue.
Below are steps I took to view the project stats:

cd "../task_test-sever-20200929-2020_09_28_05_00_34-datumaro 1.0"
datumaro project stats

OS: Ubuntu 18.04
Installation: pip install 'git+https://github.com/openvinotoolkit/datumaro'
Datumaro version (datumaru --version) : 0.1.0

Any advice would be appreciated !

Hi, looking at host='http' in the error messages, I feel like you should check ./sources/<task_..._images>/config.json and adjust the hostname.

[Loc-Vo]

The config.json file has only a single line :

{"server_url": "http://192.168.1.43:8080", "task_id": 38}

which is the correct IP pointing to the CVAT server.

[zhiltsov-max]

Try to remove http://.

Thanks @zhiltsov-max
it passed the authentication but I got another error
