OSError: Encoding error

[Seaense]

"OSError: File S001R03.edf was found but can't be accessed. Make sure it contains no special characters or change your locale to use UTF"
Am using the same file that you have used still getting the above error. And I have gone through the locale error still can't rectify the issue. Need some clear picture about it

• Which OS are you on and which version of pyedflib do you have installed?
• Can you post the complete path to the file? the name itself seems not to be the problem
• Can you access the file using vanilla python and open(filename)?
• Did you activate UTF8 encoding?

I have this problem too .
I have pyEDFlib 0.1.22 . I use win10. I can open this file . I dont know how active utpf8 .
plz help me.

You can Google "utf8 support Windows 10" and follow the instructions?

What is the filename?

Additionally, can you install the master version from the repository? It might be that the problem is actually a different one, and the error message is given by mistake. I have fixed some things with regard to that.

The file itself is corrupt. This is not a problem of pyedflib - opening with EDFBrowser will tell you additional details w.r.t that

[skjerns]

should be "fixed" now.

try installing the master version via pip install git+https://github.com/holgern/pyedflib.git, it should work now that the warning has been removed.

• What's the filename and path you are trying to access?
• Is the file generally open-able by other EDF-readers like EDFBrowser? If yes, can you upload it somewhere and link it here?
• Can you run this in your terminal and report the output echo $LANG && echo $LC_CTYPE ?
• Is there no other reported error or warning above the current error?

Hi,

thanks for answer.
This is a sleep apnea edf resmed. Maybe there's some garbage in the file?
I can read it with
with open(file_name, 'rb') as f:
contents = f.read()
print(contents)

filename and path: "data/20210803_100630_CSL.edf"

file: [https://drive.google.com/file/d/1qtUxfcElwlRVp2fh44SUJjTiERB1_iCH/view?usp=sharing]

Mhh, I cannot replicate the issue, the file loads fine for me, both on Windows and WSL.

Are you sure you are using the most up-to-date version of pyedflib? what prints if you write print(pyedflib.__version__)?

[mbelley]

Hi, I got: 0.1.22

[skjerns]

yes, that's not the current one. please install the version from master using pip install git+https://github.com/holgern/pyedflib.git, newest is 0.1.23. If you run that command and still have the same problem, than you likely have an environment problem, ie. your pip does not install into the correct python environment

[mbelley]

Thanks I'll make sure I have this version (need time...) and let you know.

All good now, thanks!

Hi. I followed this to install the newest version but I got an error message: "ERROR: Could not build wheels for pyEDFlib which use PEP 517 and cannot be installed directly". I have successfully installed PEP 517 via pip install pep517 but the problem still arises. What should I do? Thanks in advance.

[sedket]

Thanks a lot .it fixed .

Hi. I'm trying to open the same file as you (the S001R04.edf). Was your problem fixed because you have installed the newest version or because you change the UTF8 thingy? Thank you.

[skjerns]

have you tried upgrading pip?

python -m pip install --upgrade pip
