OSError: results_gen_sym.dat not found.

[mbennun]

I am trying the example using: aifeynman.run_aifeynman("./example_data/", "example1.txt", 60, "14ops.txt", polyfit_deg=3, NN_epochs=500)

It runs and then fails with this error:

results_gen_sym.dat was to be generated by this file "feynman_sr_mdl5"

I suggest checking if the file is executable, or try using print statement here to check if the above mentioned code is running

Apparently if you want to use AI Feynman 2.0, it's better to use a historical version of this repo, according to this article

I am getting the same error. @kvyaswanth This returns a [Errno 2] No such file or directory: 'feynman_sr_mdl5' @toontran I tried to use dcshapiro's fork, but it returns another error upon executing the example.py Is there any commit hash that actually works?
