Machine Learning in Elixir: error thrown in code snippet (page 44)

Running the code snippet of Chapter 2 on page 44 of version B1.0, I get the following error:

Evaluation process terminated - an exception was raised:
** (FunctionClauseError) no function clause matching in String.graphemes/1
(elixir 1.15.2) lib/string.ex:1934: String.graphemes(:ok)

I run the code on an Apple Silicon M2 and I use Elixir 1.15.4 and Erlang/OTP 26.
I have not found any solution to this issue yet.

I had the same issue with Benchee - I saw someone mention in the elixir forum that Benchee was crashing the LiveBook cells a while back. I’m also on Apple Silicon - LiveBook v0.9.3, Elixir v1.14.2.

I was curious so:
{exla_time, exla_result} = :timer.tc(fn →
apply(EXLA.jit(&Softmax.softmax/1), [tensor])
end)

{standard_time, standard_result} = :timer.tc(fn →
Softmax.softmax(tensor)
end)

IO.puts “exla is #{standard_time/exla_time} times faster”
result (one run):
exla is 66.25130208333333 times faster

On multiple runs its between 450 and 500 times faster.

Update:
By visiting the Elixir forum, I discovered that with switching to Benchee from the master branch on GitHub, the problem is solved.

Hence, I modified initial setup cell to:

Mix.install([
  {:nx, "~> 0.5"},
  {:exla, "~> 0.5"},
  {:benchee, github: "bencheeorg/benchee", override: true},
])

For the record, the improvement I noted was 337 times faster. I guess this is without using GPU, yet.

Where Next?
