can't train my datasets

I had seen the same questions, but i still can't solve it, I try to my data as yours, can you help me?

As I answered in the previous question this depends on you dataset, probably it is not good for this net.

The only way to solve it is to add the missing key in each xml file

Did you open it with a text editor (notepad if Windows or kate on linux) to paste the content here?

If not, do it and paste the content here

Again, the keys are missing. I need it in the form

<key1>
    <key2>value</key2>
etc.
</key1>

The xml file is correct, so it should work

Make sure you placed the files in the right location (see https://github.com/dBeker/Faster-RCNN-TensorFlow-Python3/issues/82)

Has your problem been solved? I encountered this problem too.
