Unable to download or generate new model

[DonaldM164]

I'm experiencing difficulties with downloading the ready model via tools/download_model.py It would seem that the content from amazon web services cannot be found, see the following from the stack trace:

[22.03.2018 20:40:47.562][WARNING][1108][cakechat.utils.s3.resolver.S3FileResolver][43] File can not be downloaded from AWS S3 because: An error occurred (404) when calling the HeadObject operation: Not Found

It then attempts to create a model which seems to complete successfully.

[22.03.2018 20:40:47.565][INFO][1108][cakechat.dialog_model.model][619] Can't find previously calculated model, so will use a fresh one [22.03.2018 20:40:47.565][INFO][1108][cakechat.dialog_model.model][621] Model is built

However no model is placed in the file path specified by the stack trace. Here is the full result of executing pythons tools/download_model.py.

Any insight into how to resolve this issue would be much appreciated, thank you!

Hello! Thank you for opening the issue.

Seems like there was a bug that only appeared under Windows OS. Please try this PR https://github.com/lukalabs/cakechat/pull/13

Thank you for your prompt response. I made the changes but the problem still persists with the same stack trace message.

@DonaldM164 Sorry for the late response

Can you please try https://github.com/lukalabs/cakechat/pull/13 again and tell if it still doesn't work?

Thank you

[DonaldM164]

It's quite alright!

Sure, I'll give it a try tonight.

[DonaldM164]

It works!
