pyaiml21 loadBrain method from Kernel not working

Question

using Python 3.8.10 on Linux Mint

I have stripped my aiml down to a minimal version to test with but the loadBrain method does not sucessfully load the brain saved.

here is the aiml code, as 'q.aiml'

    <?xml version="1.0" encoding="UTF-8"?>
    <aiml>
        <category>
            <pattern>*</pattern>
            <template>test successful</template>
        </category>
    </aiml>

and here is the python, hugely simple

    from pyaiml21 import Kernel
    k=Kernel()
    # k.loadBrain('q.brn')
    k.learn('q.aiml')
    while True:
        a=input('>')
        if a == 'quit':
            break
        else:
            print (k.respond(a,'luke'))
    k.saveBrain('q.brn')

you can see that I run it using the learn method the first time. Then on the next run I comment that out and uncomment the loadBrain line. No joy.

I just get

    >test
    unknown

as output, when I am expecting 'test successful' obviously. Note that the saveBrain method does save a non-empty file. Can I assume it is loadBrain that is broken??

Answer 1

The prolog <?xml version="1.0" encoding="UTF-8"?> is unnecessary and is the culprit of your question. Just delete it and try again.
