fast_output_file ERROR

[kpramng]

Hi,

I ran the script fast_output_file.py but ran into the below error. I was trying to read a *.out file to data frame or excel. The *.out file is attached below.

The error message also said CSVFile not available, but I have kept the folder structure as shown below.

I am pasting the contents of .out below

Hi @kpramng

Make sure you followed the steps listed here (in particular the pip install) :
https://github.com/OpenFAST/python-toolbox#installation-and-testing

From any folder, you should be able to run:

from pyFAST.input_output import FASTOutputFile
f = FASTOutputFile('5MW.out')  #<<<< Put the relative/absolute path to you .out file here
df = f.toDataFrame()

If you still have issue, let us know.

Hi @ebranlard

Thanks a lot for getting back.
I tried 2 things:

Try 1:

I followed the steps mentioned in https://github.com/OpenFAST/python-toolbox#installation-and-testing and then tried the code in https://github.com/OpenFAST/python-toolbox/blob/main/pyFAST/input_output/fast_summary_file.py but gave the error as shown below:

---

Try 2

**But, when I tried the code as shown below it ran with the .out file pasted below named as "5MW_Land_BD_Linear.out (Figure 1)"
from pyFAST.input_output import FASTOutputFile f = FASTOutputFile('5MW.out') #<<<< Put the relative/absolute path to you .out file here df = f.toDataFrame()

I couldn't upload the .out file so pasting a screen shot of it (Figure 1) (and hence messed up, sorry for that).
But when I ran the same code with the out file (screen shot in Figure 2), it failed with the error ValueError: Shape of passed values is (39, 1), indices imply (39, 39) is that because of the .out format?

Hi,

It's a bit hard to figure this out without having access to the out file.
The r-test repository of openfast contains several .out and .outb files. You can for instance download the two here:
https://github.com/OpenFAST/r-test/tree/main/glue-codes/openfast/5MW_Land_DLL_WTurb/linux-gnu

At first, let's not use Spyder and make sure it works in your anaconda terminal, where you installed pyFAST.
Launch python (type python in the terminal) and try the following:

from pyFAST.input_output import FASTOutputFile
f = FASTOutputFile('5MW_Land_DLL_WTurb.out')
df = f.toDataFrame()

If this works, but doesn't work with your out file, then we can figure out a way for you to send the out file to us.
If this doesn't work, please report your version of python, and of your packages (pip list).
If we are unlucky, maybe it's something related to the 'locale' settings on your machine.

Keep us in touch
