Error while following execution steps

[Clarit7]

Thank you for providing nice implementation. However, I got stuck in executing basic test code and really want some helps.

PANIC! Exception in child worker: MAX RAISE
Traceback (most recent call last):
  File "/home/jaylee/Programming/ec/bin/../dreamcoder/enumeration.py", line 302, in solveForTask_ocaml

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

I tried to execute bin/text.py in both of my own env(ubuntu 18.04 LTS) and singularity container env, but every time I got that error. I also checked past issues: https://github.com/ellisk42/ec/issues/78 , https://github.com/ellisk42/ec/issues/64 . None of them didn't works for me. Do you have any idea about this error?

I use: ubuntu 18.04 LTS singularity 3.8.0 python 3.7.6

Which test code? Is this 'python text.py -t 20 -RS 5000' , or something else?

The test code was 'python bin/text.py -t 20 -RS 5000'. I executed it in project root directory.

Hmm. yeah, that should have worked, so far as I can tell. I've encountered that same error you got when I was messing around trying to set up my own scripts, but I don't remember why or how I solved it.

[Angular-Angel]

Oh! Did you go through the steps to build the OCaml binaries? I think that was part of it.

No I didn't. Thanks for advise. I'll try to build the OCaml binaries as you told. :)

[Angular-Angel]

Did that solve your issue? :0

Your suggestion worked perfectly! Thank you!

[Angular-Angel]

Haha glad to hear it. Have you been able to get the program working generally? I was able to get the simple test demo working, and some other stuff, but I ran into a wall later: https://github.com/ellisk42/ec/issues/77

I didn't tested yet with my own domain. I'll try it in the near future 👍

[Angular-Angel]

Awesome, thank you!
