No module named Base

[cveillet]

Sorry for this basic question (new to SharpCap!) I must be missing something very basic...

I want to launch SharpCap from the command line with a script.

Here is the command:

Code: Select all

C:/"Program Files/SharpCap 4.0 (64 bit)/SharpCap.exe" /runscript "c:\Data\RINGSS\python_code\SharpCap.py"

The script is:

Code: Select all

import clr
clr.AddReference("SharpCap.Base")
clr.AddReference("SharpCap.Interfaces")
from System import AppDomain
clr.AddReference([t for t in AppDomain.CurrentDomain.GetAssemblies() if t.GetName().Name == "SharpCap.App"][0])
del AppDomain
SharpCap.SelectedCamera = SharpCap.Cameras[1]
SharpCap.SelectedCamera = SharpCap.Cameras[0]
SharpCap.SelectedCamera.GetControl(CommonPropertyIDs.Exposure).Value = 0.002

Program is launched, the script is used but fails with this message (in the IronPython Console)

Code: Select all

IronPython 2.7.11 (2.7.11.1000)
[.NETFramework,Version=v4.5 on .NET Framework 4.8.4645.0 (64-bit)]
Type "help", "copyright", "credits" or "license" for more information.
>>> 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Data\RINGSS\python_code\SharpCap.py", line 7, in <module>
ImportError: No module named Base

The last three lines of code in the script work well from the code snippets area of the Console...

I am using SharCap Pro (v4.0.9538, 64 bit)

Thanks!

Hi Christian,

I'm not sure that I can work out why you have the first 6 lines of the script in the first place - those duplicate things that SharpCap does for you when it initializes the python language (and it should do those things before your script it run). The last 3 lines of ths script should be sufficient. However there is a bug in SharpCap 4.0 that means that the /runscript command may not work. This is fixed in SharpCap 4.1.

I do wonder if the duplication of the clr.AddReferences() in the first few lines is causing the issue.

cheers,

Robin

Hi Robin,

I initially thought that I didn't need to add anything to plain code already working from the scripting tool inside SharpCap. As it didn't work out, I thought I would add more information in the script.

I quickly checked that indeed removing the first six lines does not work either. The message I get when opening the console to see what happened is:

Code: Select all

>>> 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Data\RINGSS\python_code\SharpCap.py", line 1, in <module>
NameError: global name 'SharpCap' is not defined

The good news is that the script is sent to SharpCap through the command line file name, which is good. It just fails to run, as if it were executed too early...

Is SharpCap 4.1 already available?

Thanks,
Christian

Hi,

SharpCap 4.1 is in release candidate stage at the moment - you can download the latest candidate here : https://www.sharpcap.co.uk/sharpcap/sha ... p-4-1-beta

If you stay with 4.0, try putting the script into the 'Startup Scripts' section of the settings - those are handled better than the /runscript option in SharpCap 4.0

cheers,

Robin

Thanks!
I downloaded the 4.1 beta and I am working with it.
I will come with questions if any...

The startup scripts option works very well! Thanks...

So far so good... with probably more questions as I progress toward using SharpCap to automate a seeing monitor / turbulence profiler.

Cheers,
Christian
