Hi, there is an error when I try to run "falconz -d (dir) -r deformable" in falconz 2.0.27. If you have any ideas for solving this, please let me know. Thanks!

Hi @christanmod,

I would need more info to help you out.

• What data is it?
• OS
• python version

Etc.,

Hi @LalithShiyam,

Thank you for your prompt reply. I think data is not a problem because falcon works on my Windows PC for the same datasets, but not on this Windows workstation. -python version: Python 3.9.16 -OS: Windows 10 Pro for Workstations

Do you have permission errors? When you create the environment? Try c3d --h in your environment and let me know what you see.

The issue happens in windows often. When you are in a shared resource - e.g: a server or workstation.

@Keyn34 has more experience in this. But it really looks like a permission error, where you don't have permissions to run the binaries downloaded by falcon. We do have a set permissions function, but this doesn't seem to help.

I would wait for @Keyn34's response, as he dealt with it often. But AFAIK there was no clear solution. I might be wrong though.

Cheers, Lalith

Hi Lalith,

Yes, I agree, it should be related to permission to run the binaries. Because "c3d --h 'c3d' is not recognized as an internal or external command, operable program or batch file." I'm looking forward to the further response, and I may try to set the binaries dir to the environment variables to see if it helps.

Thank you!

[LalithShiyam]

Good, I would also see how you could fix the permission issues. We would be googling as well 👍🏼

[Keyn34]

Hi @christanmod, this is a problem we usually encounter when the user settings and permissions within Windows are not 100% resolved. To fix this, a few restarts and editing the registry might be necessary.

A quicker but not guaranteed fix you could try first is the following:

• In the venv directory you have installed falconz, navigate to the site-packages folder and search for falconz.
• Within this folder, locate file_utilities.py. Open it and search for set_permission().
• Exchange this line in the located function with a simple pass.
• Save the file and try running falconz again as before.

Let me know if this works! Thanks

Hi @Keyn34 , Thank you for your reply. This solution works for my own PC like in issue #52. But for the workstation it doesn't work, it was frozen for several hours without error info if I only passed the line in set_permission, and c3d --h still gave error. After that, I tried to put the directory of binaries into the environment variable. Then it worked. Hope this information is helpful to you.

[LalithShiyam]

Hi @christanmod fantastic. Would you be kind enough to mention the steps you did or even make an addition to readme as a PR. We are planning to make a FAQ section and we could include this there. Cheers, Lalith

Hi @LalithShiyam ,

I have added an additional Q&A.md, hope it helps.
