LabVIEW
labviw call python and build applications
Solved!
I'm calling python with labviw，E.g “PythonNode_AddTwoDoubles.vi”.
In vi, it is able to operate normally.
But when I build the application,error 1663 will occur. and .py has been added to the source file.
How should the relevant configuration file?
I assume the path is wrong. It will end up in the data directory of the executable by default.
Add some path checking and error checking\reporting to the code, and you'll get more feedback.
Search LabVIEW like a graph! Thank you very much for your reply.
But I have Python module path is specified as a constant, the error 1663 still exists

Is the problem due to the python installation directory? I think the python DLL should be in the system path. And by default the python installation will not copy DLL to the system path.
Can you please share the solution.
@Humbert1985 paraphrased:
I have solved this problem:
1) Python ??? bit, LabVIEW 32 bit, Win10 64 bit: dev.env is Ok, EXE is Error
2) Python ??? bit, LabVIEW 64 bit, Win10 64 bit: dev.env is OK, EXE is Ok
I would expect that LabVIEW and Python bitness need to match. So 32 bit LabVIEW requires 32 bit Python. Not in development environment, but for executables.
The problem I encountered is using labview2018-32-bit and python 3.6.0-32-bit and computer win7-64-bit. In the example, python node reported 1661 errors. How to solve this problem？
