TypeError: lstm.run(....).map is not a function

This error message is indicating that you are trying to call the `map` function on the output of the `run` method of an object called `lstm`, but `map` is not a function that can be called on the returned value.

There could be a few reasons for this error, including:

1. The `run` method of the `lstm` object may not actually return an iterable object that can be mapped over. In this case, you may need to modify your code to handle the output of `run` differently.

2. It's possible that there is a typo or mistake in your code that is causing the `map` function to be called on the wrong object or in the wrong context.

3. There may be a problem with the `lstm` object itself, such as it not being properly initialized or configured, which is causing the error to occur.

To fix this error, you may need to review your code and/or consult the documentation or source code for the `lstm` object to determine the correct way to use its `run` method and handle its output.
