Model file cannot be opened for saving!

[helgasvala]

Hey!

I'd had some problems before with loading the base doc file and loading the model file but I had to download StarSpace again and now I'm getting a new error.

I'm using this tutorial https://towardsdatascience.com/learning-note-starspace-for-multi-label-text-classification-81de0e8fca53

My train and test files look like this:

'market open household __label__1',
 'guarante __label__1',
 'syring contain microgram correspond million intern unit interferon beta __label__0'

and I'm running

(base) Helgas-MBP:Starspace helgasvala$ Starspace/starspace train -ngrams 2 -minCount 10 -thread 4 -trainFile topics2/train_2.txt -model topics/starspace_2.model

I get

Saving model to file : topics/starspace_2.model
Model file cannot be opened for saving!

I can't find anything about this problem except for the code where the error message is written. What can I do to get around this?

Thanks for your help!

@helgasvala Hi, does the directory topics exists and you have the write permission? I think that's the only reason the model saving could fail. Have you checked that?

[helgasvala]

It worked with a completely new installation, something must have gone wrong when installing. Thanks. :)

@helgasvala You're welcome. I'm glad that works. Closing the issue now.
