Hi, I'm trying End-To-End Confidential PyTorch Workflow. When I run gramine-sgx ./pytorch pytorchexample.py, I got

Detected a huge manifest, preallocating 128MB of internal memory. Gramine detected the following insecure configurations:

• loader.insecure__use_cmdline_argv = true (forwarding command-line args from untrusted host to the app)
• loader.insecure__use_host_env = true (forwarding environment vars from untrusted host to the app)
• sgx.allowed_files = [ ... ] (some files are passed through from untrusted host without verification)

Gramine will continue application execution, but this configuration must not be used in production!

Can someone help me?
