NS2_Interop.dll, System.DllNotFoundException

[kallpreb]

Same problem as in issue #48

ConnectionTimeoutError: Timeout after 10.0 seconds. Could not connect to 127.0.0.1:49520
Instantiating 'NanoScanServer' raised the following exception:

Traceback (most recent call last):

^^^^^^^^^^^^^^^^

Cannot start the 32-bit server.

I have to use a new computer now and got the same problem as in 2022. Solution to take an older computer is not possible now.

Hi, honestly it has been a while since I've touched this project, but I see that you using Python 3.11, which I have not tested against (nor do I have the ability to test with anymore as I no longer have access to a NanoScan device).

Some things you could try:

• Try copying these two files to C:/nanosquared_include/ (See this section of the code for more information)
• Checking against conda-environment.yml to see what the exact versions of the package I used back then, and see if that allows you to run the code "out-of-the-box"
• If a newer python/package version is to be used, you could try recompiling the dlls: https://github.com/sunjerry019/nanosquared/tree/master/src/nanosquared/cameras/csharp Just open NanoScanLibrary.sln in Visual Studios (not VS Code, but the actual one!) and recompile the binaries. You might need to massage the paths in the file a little but it should just compile normally.

For testing purposes, I suggest using a 32-bit Python environment (e.g. here) and using nanoscan_32_dotnet.py to test.

Hope this helps, if not, don't hesitate to write back :)

Hi @kallpreb, were you able to solve your problem?

Hello, I was very busy the last 2 weeks and had no time to deal with this issue. When I had this issue two years ago I had two computers with exactly the same python environment. With one computer it works with the other not. I also tried with anaconda and the same package versions you use without success. My solution the last time was to use the older computer. I will check the 32-bit python as you suggested. Best regards Von: Sun Yudong ***@***.***> Gesendet: Mittwoch, 8.
