Gallery apps not working fully

[leungi]

First off, thanks for the great resource!

I tried containerizing a simple demo myself, and can't get it working on a CentOS (though it works on Windows); however, your image works 👍

But an issue with the gallery piece (only spacy demo is working), as shown below:

Exact error message is:

URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)>

Hi @leungi

Thanks so much for reaching out. I will take a look ASAP.

Please confirm that your are running this locally after having cloned the repo and followed the installation instructions.

In the mean while I think your video image is awesome. How do you create something like that?. I would like to be able to do the same.

Thanks.

Thanks for prompt reply @MarcSkovMadsen.

I didn't clone repo, and mounted container by pulling from your Docker Hub repo.

I'll clone the repo, build from it, and update this post.

For the .gif, I use screentogif.

Hi @leungi . I found this on https://stackoverflow.com/questions/50236117/scraping-ssl-certificate-verify-failed-error-for-http-en-wikipedia-org. It seems that on MacOs you need to install some certificates manually. It's described in the link.

Let me know if it can help you. Thanks.

Thanks for reference @MarcSkovMadsen; I'm actually on Windows and I typically bypass this with conda config --set ssl_verify False.

I'd need to bash into your docker container and try; will update.

Apologies for much delayed response @MarcSkovMadsen.

It seems that internal cyber-security blocked all public facing IP, and ./src/pages/gallery/index.py source most of the content directly from github.com, hence the error.

The best solution is to download the hosted app locally and read from disk.

Thanks again for your suggestions.
