rs-test fails, Import-Error

[tobidurr]

I installed rsudp on two separate machines, one running Win10, one Win11. As far as I can see the installation works successfully. When I try to run rs-test in the rsudp environment I get the following error message on both machines.

 PS C:\Users\Abberior_Service> rs-test

During handling of the above exception, another exception occurred:

I am not sure if this is an issue with rsudp but googling the error code did not help. I am therefore not able to run rsudp currently.

I'm also having this same issue. Did somebody find out a workaround?

[rodonile]

I haven't been able to solve the issue, but it's related to the obspy dependencies. If you comment all of them out (while also running rsudp without deconvolving of course), then it runs fine.

I have the same problem, someone was able to solve it?

ImportError: Could not load shared library "libsignal_Windows_64bit_py37.pyd"

@tobidurr @rodonile @Jos3111 Thank you for the reports.

This indeed appears to be an upstream issue with an obspy dependency. How did you install obspy and what version are you using? Also, what version of Windows? If you don't want to use the workaround of commenting out the obspy dependencies, consider opening an issue with obspy. It looks like they've had a similar issue to this in the past.

We will close this issue but feel free to re-open it if you think that we missed something.
