Expected Behaviour

Deploy new serverless function according to opencv documentation.

Current Behaviour

The path serverless/common/ was mounted into the container as a volume. Double checked that serverless/common/openvino/python3 is executable. See the following log.

Possible Solution

Tried provided solutions mentioned in #5205, #2820, #5351 with no success.
We tried to build the docker image for dextr on our own writing a Dockerfile. When deploying it with nuctl also

Error - fork/exec /opt/nuclio/common/openvino/python3: no such file or directory
                          ...//nuclio/pkg/processor/runtime/rpc/abstract.go:239

occured.

Steps to Reproduce (for bugs)

1. following the opencv documentation Semi-automatic and Automatic Annotation.
2. If the following nuctlcommand is run the mentioned problem occurs.

nuctl deploy --project-name cvat \
 --path serverless/openvino/dextr/nuclio \
 --volume `pwd`/serverless/common:/opt/nuclio/common \
 --platform local

Hi, @k-spit

It is a known problem with WSL. Unfortunately we didn't investigate a root cause yet. If you can help, would be great.
Also you can try to use a virtual machine instead, for example I am using VMWare on Windows 10 with Ubuntu 20 and nuclio functions work well.

I am having the same problem and have tried a lot of various versions and still the effect is the same : /

[Fafa87]

Well, I put up Ubuntu on Oracle VM VirtualBox and got to the same result:

Error - fork/exec /opt/nuclio/common/openvino/python3: no such file or directory

    ...//nuclio/pkg/processor/runtime/rpc/abstract.go:239

[Fafa87]

Above I used the repo cloned on Windows and accessed in guest vm as shared folder.
But when I checkout a clean repo inside guest ubuntu, purged entire docker and building it up again -- it worked! I will try to track it down - perhaps it is something silly :)

EDIT: well, there is a LF vs CRLF... :)
EDIT2: clone 2.3.0 but with LF and was able to set up a dextr!

[Fafa87]

@k-spit It seems that the problem is caused by getting the repo with CRLF.
You can try cloning it with LF endline and it should run smoothly as it does for me now.
It would be great to have double confirmation that it was indeed the issue.

@bsekachev FYI ^

[bsekachev]

@k-spit Could you please try advice from @Fafa87?

[k-spit]

@Fafa87 Do you mean when git cloning ? Can you explain how you cloned it just with LF instead of CRLF ?

[Fafa87]

Yes, when you clone git normalizes the endlines. You have to change that setting before making a clone:
git config --global core.autocrlf input
git config --global core.eol lf

Those worked for me but check endlines manually before installing.

[k-spit]

@Fafa87 that solution did it. Thank you :)
