Works for me with pip install sixdrepnet==0.1.5. 0.1.6 seems to be broken.

Can you specify the issue?

Hi,

The issue here is that source code files listed below have the statement "import utils":

• create_filename_list.py
• datasets.py
• demo.py
• model.py
• regressor.py
• test.py

Python version 3.10 and later have a system-wide Python package, called 'utils', that has a higher precedence over any local file instance called utils.py. As a result, all the 6DRepNet files listed above refer the system-wide Python module 'utils' instead of the desired local counterpart. Since the system-wide 'utils' is targeted for totally different purposes and excludes the function compute_rotation_matrix_from_ortho6d(), we see the error message
AttributeError: module 'utils' has no attribute 'compute_rotation_matrix_from_ortho6d'

There are at least two workarounds to solve the issue:

1. Rename the 6DRepNet file from utils.py to something different, like sixdrepnet_utils.py, and update all the references "import utils" accordingly (i.e., like "import sixdrepnet_utils".

   • In general, any Python project should discontinue creating and using a local project-specific file utils.py as it causes a serious conflict with the system-wide Python module 'utils'. Public Internet has quite many sites discussing about the issue in general, like the example ones below:
     • Stop naming your python modules "utils"
     • Python Pro Tips: Organizing and Simplifying Your Codebase with Utilities and Helper Functions
     • Utils files are not so useful and helper classes are not so helpful!

2. Since 6DRepNet gets build in a package, called sixdrepnet, the most straightforward fix might be to replace all the references "import utils" to "import sixdrepnet.utils".

In general, please discontinue completing the package installation using the commands "python setup.py install" and/or "pip install -e .". These are not supported in PIP version 24.3.1 and later. A simple alternative way would include the following:

1. Create an appropriate Wheel package.

   python setup.py bdist_wheel

2. Install the package using PIP from the Wheel package explicitly.

   pip install <path_to_wheel_file>
