Intel Fortran and Python f2py

[Ian_K_]

Last year I was able to convert a  block of FORTRAN subroutines into a PYD format library using f2py.  I started a command environment using

and was able to simply use (I am showing a common Fibonacci number test case which appears in multiple f2py examples, my codes were more elaborate)  

python -m numpy.f2py -c fib1.f -m fib1

This worked with no problems.  Now with my update to ONE API, the same logic fails (apparently at some point after I start the  compile process.

The initial command shows a successful CMD setup

When I check in the app data I see that wrappers were successful and the failure appears to be associated with compilation. 

I am not sure if this post is appropriate but  I have checked with numerous python with no luck at all.  The fib1.f file is attached.

[mecej4]

The traceback and the messages are from your Python build system, not the Fortran compiler.

As for the Fortran source file fib1.f is concerned, you have to make sure that, when the subroutine is called, the array argument A is has a length of at least n.

[Ian_K_]

Thank you for the comment, first I am only using fib.f as a test because it commonly appears in NUMPY documents, my subroutines are more complex.  The main point is the f2py worked fine before and I was able to use the library in PYTHON.   I realize that the output lines are python comments, but my problem is that it worked last year with version 19.1. Since the Fortran compiler updates to ONE API it no longer works and it appears that the new compiler output (no other steps are visible in the screen output) is not compatible with F2PY, that is why I am seeking help here.   

I noted that when I check python versions I see that in fact I am using Intel Python (which may have been updated in ONE API. 

So to test an alternative I ran used Anaconda (that I use with Spyder for my Python) to create a cmd screen and tried to set the environment by copying the two setvars batch files to my test folder and they ran with no error.  Executing the Python f2py line then cannot find the Fortran compiler.  So a new question, how can I make f2py see the compiler in a command screen.

Thanks in advance for any help 

[mecej4]

Before attempting to run a Python script or program that is expected to call the Fortran compiler, check whether the environment is correctly set up by entering the command ifort . If you do not receive the short response from the compiler with version information, that is an indication that you should run the Intel Fortran startup script setvars.bat, in the same way that you say you did with Anaconda, etc. (whatever that is, I do not know).

[Ian_K_]

I have tested this approach 

I started with a cmd generated from anaconda (a popular framework for python users through Spyder)

I negotiated to my test folder and ran a copied version setvars with apparent success.  See (1) below

Next I entered IFORT but it was not recognized

Next I used SET to look at the environment (2) below but could not see a pointer to IFORT.  This is getting to the edge of my system skills, I have more than 50 years experience with FORTRAN as a user but have little systems experience. so after I tried to attach the two SETVARS batch files I needed to have, to change them so that so they form 3 and 4 as TXT files. The system still rejects these apparently txt files so I cannot attach them

Note that I am using VS2019 for my FORTRAN and the same issues with IFORT arose when I started from a plain CMD start.

When I opened a ONEAPI CMD start a much more detailed startup occurred and IFORT worked 3 below

another try to attach files

[mecej4]

I am not sure whether the following suggestion will help, but trying it requires almost no effort.

Instead of running a copy of the Intel Fortran setvars.bat file, run the original batch file using its full path and provide to it the two command line options "intel64" and "vsnnnn" with "nnnn" replaced by the year that pertains to your version of Visual Studio.

[JohnNichols]

https://numpy.org/doc/stable/f2py/windows/intel.html 

This guide provides the method, I would make sure you can get this working first - following their exact steps, before you move onto harder stuff.  They list the current problems with Intel, interesting really. 

You do not need to plonk down all of the output.  

[IanH]

The python traceback suggests that it is getting confused by whatever version string the compiler executable is returning.  The layout of version strings does change from time to time.

Running a test here with numpy 1.20.3 on python 3.9.5 (and not the oneapi distribution of python - I don't have that installed), I can see that the python script is fragile - it is confused by spaces in installation paths and target file paths.  But the version string is being extracted correctly.

What are your python debugging skills like?  It would be handy to know the contents of the "output" variable in the faulting call to re.search. 

[Ian_K_]

First, thank you to all three of you (Mercej4,John Nichols and IanH) who responded.  I now seem to have a viable process.

1   Create a CMD from Anaconda 

2   As suggested: Run SETVARS.BAT with the full path "C:\Program Files (x86)\Intel\oneAPI\setvars.bat"

3   Execute Python as installed by Anaconda with the full path.
      C:\Users\iking\anaconda3\python -m numpy.f2py -c fib1.f -m fib1

It thus appears that it is Intel's Python that is the culprit.

I should note that using  the ONEAPI for the CMD or a simple setup from the start box then the full path for Python failed immediately due to missing dlls.

Using f2py works for me on a different machine that has (and also uses) the intel python distribution (2023.1), so I suspect the culprit is something to do with your particular set-up.

I don't follow your last sentence, but as a general statement - environments need to be configured appropriately for the tools that you are running in them.

[Ian_K_ · Accepted solution]

I have now come to more or less understand the issue, which I suspect is related to my configuration either of FORTRAN or ANACONDA

I can get at f2py by using the anaconda CMD structure and then setting up a ONEAPI environment and then finally accessing Python through a full path to the Anaconda version of Python to avoid the Intel Python.

The ONEAPI  CMD command structure will fail because any attempt to execute Python requires the Anaconda environment ( something I have to work on).

In a sense this is my accepted solution, and it is a combination of the comments of all who responded.

Thanks to all
