ImportError: libGL.so.1: cannot open shared object file: No such file or directory

Question

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

Kevin Zhu 26

Hi fellow experts,

I hope you're doing well.
I'm currently experiencing an issue with azure - I cannot import module cv2 because there's an ImportError: libGL.so.1. I've searched far and wide on the web but nothing really seems to help me. See the picture below.

I'm running my FLASK application from sublime text and the command terminal, and I've successfully deployed this application to Azure. See the picture below.

I really don't understand what I need to do in order to resolve this issue, and I'm not understanding some of the forum solutions people are posting towards this question. I'm very new to web development and I was hoping I could get your help on this.

To see my full code, here is the link to it: https://github.com/kevinzhu99/imageView
If you know of any solutions to this problem, or any questions you have with my problem to gain more context, please let me know and I will get back to you as soon as possible.

Thank you in advance!

Update: My azure page will only load my initial page/ index page, but not the page I actually want (shnGetCamImg) because Azure isn't reading cv2 properly. I want to say that I'm confident and I have everything I need (if not more) in my requirements.txt file, but please correct me if I'm wrong.

Once again, I'm fairly new to Azure so if there's anyway to resolve this issue I'm willing to take that route. If there may be any rare chance that you would need my email, it is kevin.zhu87@Microsoft Corporation .com.

Thank you in advance!

How are you deploying @Aadil Khan ? Are there any errors in your deployment log?

@sandeep , adding a dockerfile won't work in this case, unless if you're deploying an image. Do you have any deployment errors? How are you deploying?

Hi @Kevin Zhu ,

Please see the answer I posted here with regards to missing modules.

I also noticed shnGetCamImg wil fail because cameraip is not being set if the request method is GET. Your if condition terminates after pic_type = (request.form['picOptions']).

Hi @Ryan Hill , I responded to your last email and to the module not found post. Deployment isn't an issue, I've been following the Kudu deployment. It's when you load the webpage and get onto the second page where my page crashes. On my local computer, this entire webpage works 100% fine with no errors, it's when I try using it on Azure where everything starts failing. I don't understand what's going on - especially now because my webpage is giving me a different error now and I don't know what to do. If you have any other questions about my code, please let me know and I will get back to you as soon as possible.

apt-get install --reinstall libgl1-mesa-glx:i386 as I am new with webapp not sure this is right syntax as do not see tentative of execution in log .

Hi @Arnaud De Jaegher ,

You can utilize a .sh file containing your apt-get install --reinstall libjl-mesa-glx:i386 and set that .sh file to your PRE_BUILD_COMMAND app setting. See https://learn.microsoft.com/en-us/azure/app-service/configure-language-python#customize-build-automation for more details on how to customize your build.

Ryan

I actually solved it by taking the docker route... I created DOCKERFILE see next

and followed the protocol as per https://code.visualstudio.com/docs/containers/app-service
this works perfectly fine now. I ll try your option too . thanks again for helping.
