[Examples] Python Example Stuck Without Any Error Message

[KeplerC]

Description of the problem

I just installed graphene and make the manifest by the document. The installation and manifest compilation do not report any error message. However, as I ran graphene-direct ./pytorch pytorchexample.py, and the program stuck indefinitely. This occurs for both vanilla python and pytorch example.

(base)  $ graphene-direct ./pytorch pytorchexample.py
error: Using insecure argv source. Graphene will continue application execution, but this configuration must not be used in production!
error: Forwarding host environment variables to the app is enabled. Graphene will continue application execution, but this configuration must not be used in production!
[P2325784944::] debug: Host: Linux
[P2325784944::] debug: LibOS xsave_enabled 1, xsave_size 0x440(1088), xsave_features 0x1f

Steps to reproduce

After installing the graphene,

cd Examples/pytorch
DEBUG=1 make
