Re: Import error using an OOT

Jim,

 

Thanks for jumping in. You got me focused on the real issue. I put the path to the file in config.read() and everything now works.

 

I let myself wander off the path to the real problem (pun intended).

 

Thanks also for Johannes' comment regarding './'.

 

Jim

This thread seems to have gone for a while with a bit of thrashing. To recap:

 

> I have created an OOT which when I incorporate it in my flowgraph shows the following error:

> Failed to evaluate import _expression_ 'import ft8'

 

This error is very clear. Python was not able to import your ft8 module.

 

Next,

Also very clear; in your module __init__ you are trying to get a value from the 'main' section that does not exist.

 

But your config file has a 'main' section. So, then, the obvious implication is that your file is not being read.

 

As Johannes Demel pointed out,

 

> The `./` part in you file name is relative to the folder where you run Python. It is not relative to the `.py` file.

 

Even if you don't specify "./", it is assumed. So, either make sure that your config file is in the directory where you start the python process, or create some path to where your config file(s) live and include it in the argument to config.read().

I tried omitting the ./ and still get the same error. I thought ./ indicated the current directory.

 

The .conf file is in the same directory as the .py file.

 

I tried using read_file and got a MissingSectionHeaderError.
