Hi, sorry, NMatrix isn't maintained anymore and hasn't been for some time. On Sat, Mar 12, 2022 at 10:10 AM Kostas ***@***.***> wrote: > I have similar issue on MacOS...

When I run your code and try to instantiate the object with `NeuralNetwork.new()`, I get the following: ``` TypeError: nil can't be coerced into Integer from /Users/jwoods/Projects/nmatrix/lib/nmatrix/nmatrix.rb:117:in `*' ``` I...

Hey, sorry, but if you want us to help you debug your code, you need to provide a minimum working example. What's the minimum amount of code that reproduces this...

Even with that information, I can't run a debugger on it without a minimum working example.

It's not happening for me. But I'm looking through your segfault and seeing this: `/var/lib/gems/2.3.0/gems/nmatrix-0.2.4/lib/nmatrix/math.rb:710: [BUG] Segmentation fault at 0x00000000000008` The fact that you're dealing with a memory address near...

Ohhhh, that's different, and could perhaps explain why I wasn't seeing the same problem, since I'm on MRI and not JRuby. Interesting.

If someone can produce a reliable *minimal* test that causes the crash, that would be immensely helpful. Even if it's random, sometimes you can do something like ``` 10000.times do...

Honestly, I'm not sure. I don't see where it _is_ changing `IO.each`, but it's been a long time since I messed with any of the IO stuff. I'd suggest starting...

Unfortunately, packable is pretty necessary for the MATLAB-format matrix readers and writers. If someone wanted to rewrite those, it'd be fine to shed packable. @moloh Please open an issue here:...

@v0dro I think the idea is that we probably need to come up with a solution in NMatrix that doesn't require packable. Or perhaps that we should make Matlab IO...
