I followed the instructions precisely, but when I type solve-semantle, it says 'solve-semantle' is not recognized as an internal or external command, operable program or batch file. What do I do?

Hello,

First, thanks for developing this tool, it is quite funny to see how fast it solves Semantle games :)

However, I stumble upon this behaviour:

$ .local/bin/solve-semantle
Semantle Solver!

Step 1
----------------
157244 solutions remaining
Recommended: object
Alternatives: [person, place, action, adjective]
----------------
Enter your guess: hello
What was the similarity? 4.04

Step 2
----------------
306 solutions remaining
Recommended: neuroanatomical
Alternatives: [mupirocin, lymphocytic, recombinants, amisulpride, bullae]
----------------
Enter your guess: neuroanatomical
What was the similarity? -0.68

    return sqrt(add.reduce(s, axis=axis, keepdims=keepdims))
numpy.AxisError: axis 1 is out of bounds for array of dimension 1

Note: the secret word was "pace".

A brief print()-based debugging session reflects Solver.recommend() calls _get_words_closest_to_mean() with an empty "words" tuple. This seems to happen only when, at some point in the process, a negative similarity whose absolute value is greater than the uncertainty was submitted.
