NotADirectoryError: [WinError 267] The directory name is invalid

[Hoogashaga]

Hi, I still have below error due to NotADirectoryError: [WinError 267] May I know how to solve the problems? You can read the log I posted.

Can you try with an absolute output path? And make sure the folder exists first?

What version of flirpy are you using?

[Hoogashaga]

How to know my current version?　I installed the lib a week ago by "pip install flirpy". I think it's the latest version. Yeah, I tried like "python C:\XXXXX\venv\Scripts\split_seqs.py --input "*.SEQ" --output "out" --width 640 --height 480" But same problem, NotADirectoryError: [WinError 267] The directory name is invalid

[jveitchmichaelis]

I meant for the output folder, e.g. "C:\XXXXX\out" and check that out exists. Yeah if it's from pip it's probably OK. I believe that error means something is being passed a filename instead of a directory. Could you maybe edit the file (C:\XXXXX\venv\lib\site-packages\flirpy\util\exiftool.py) and put a print statement where you get the error (line 75) to see what cmd and cwd are?

[Hoogashaga]

The out is generated with subfolder having same name as my SEQ file, but it's empty in the subfolder cmd=>['C:\XXXXX\venv\lib\site-packages\flirpy\bin\exiftool.exe', '-ext', 'fff', '.', '-w!', '.txt'] cwd=>C:\XXXXX\out\sample\raw

[jveitchmichaelis]

And can you try running that command manually? i.e. you should have a folder full of fff files and this command should extract the metadata from them.

Ah so if I understand correctly, your raw folder is empty at this stage?

[Hoogashaga]

"can you try running that command manually" =>I'm not sure what you mean here Yes, raw folder is empty. Same problem.
I also print line 112 in split_seqs.py => ['C:\XXXXX\venv\sample.SEQ']

[jveitchmichaelis]

Underneath, all flirpy is doing is running a chain of Exiftool commands on your data. Actually the version you have may be using flirpy's SEQ decoder which is possibly failing, though I don't think that's the problem here. You'd be getting an error later on if that were the case. It seems like right now it's failing to split a single file.

What I was suggesting was to manually run the command that subprocess is trying, e.g.

C:\XXXXX\venv\lib\site-packages\flirpy\bin\exiftool.exe -ext fff . -w! .txt

So, first we take each SEQ file and we split into FFF files - this step seems to have failed, not sure why.

Then flirpy will use Exiftool to extract metadata from each of the fff files (i.e. fff -> txt) and this is used for radiometry.

Finally, firpy will open each fff file in turn, extract the raw data and use the radiometry to save it as a png/tiff.

So this sounds like it may be some issue loading sample.seq. Are you sure the height is 480? Some FLIR cameras have height equal to 512. Let's try and figure out why your SEQ file isn't loading properly first. I'll write some sample code for you to try loading the file manually, but I can't do that right now.

[Hoogashaga]

Yes, it's 640*480 I tried below from exiftool forum exiftool "C:\XXXXX\venv\Scripts\sample.seq" -b -RawThermalImage >C:\output Access is denied.

Is it possible that my company computer blocked any new write and then leading to NotADirectoryError: [WinError 267] The directory name is invalid ?

[jveitchmichaelis]

It's possible, but permission errors can be fairly common with Python on Windows. Have you tried running powershell/prompt administrator?

[Hoogashaga]

Yes, I used prompt administrator.

[jveitchmichaelis]

If you're unable to modify the directory yourself (i.e. not using Python) then I'm not sure I can help until you figure out why that's happening, it doesn't seem to be an issue with flirpy specifically.
