TypeError #2

Hello, thanks for putting this together! I've been really struggling to find a reliable way to train a custom model and this looks like it's almost perfect for what I need.

I followed your instructions exactly and everything goes fine just until step 11. I get the following error. I did double check the folder locations are as required. Also, I made sure that the label map capitalization is the same as the XML files.

Hello, I think this is due to a quotation error in the label map file. Make sure that the quotations in your label map file are of the form '' (straight quotations) and not of the form ‘’ (curved quotation).

Thanks for raising this issue, I have updated the label map step in the article. Please change the label map file accordingly and retry again!

Good catch! Yes, that error is resolved. Thank you!
