Sample Execution Error

[pico-jp]

Hello.
I am trying to execute the first example code of AI-Feynman, following its GitHub repository procedure.
I have done $ pip install aifeynman, and executed the below codes at the REPL.

import aifeynman
aifeynman.get_demos("example_data") # Download examples from server
aifeynman.run_aifeynman("./example_data/", "example1.txt", 60, "14ops.txt", polyfit_deg=3, NN_epochs=500)

The code has been started, but it output an error message "STOP DEATH ERROR: missing file args.dat" with the following stdout statements.

Checking for brute force +

My environment was constructed on an AWS VM based on the Deep Learning AMI of Ubuntu 18.04,
and its pre-installed conda environment with py36 & torch was activated.

I would appreciate it if you could tell me how to solve this problem. Thank you very much.

Are you sure it is not a problem of rights ? maybe open up the file permissions with chmod (see §4 of https://towardsdatascience.com/ai-feynman-2-0-learning-regression-equations-from-data-3232151bd929 )
