Hi,

My final output is incorrect.
The prior functions have passed.

The final function is not getting any syntax errors.

Not sure what is wrong. The output is listed below

Thank you for any help

HI @NeilA

Your single example is wrong, so there is a problem with your code within model(). If you post that section of the code in a DM to me, I will have a look for you.

Hi Kin,

Is it ok to email the code by a response to your email?
(As I don’t want I violate the rules)

Thank you,

Neil

Hi Kin,

Thank you for your response.

The code in the model function is listed below:

Hi @NeilA ,

Two areas need attention in your code:

  1. single_example
    this should be taken from examples, because in examples, all the unwanted
    characters such as spaces, are filtered out.
  2. single_example_ix
    you need to use char_to_index to turn the char in single_example into the digit
    represent the char. Here is how to do it:
    single_example_ix = [char_to_ix[c] for c in single_example_chars]

Hi Kim,

Thank you again for your response and for taking the time.

Yes that worked. Using examples to update single_example instead of data_x solved the issue.

Thank you,

Neil A
