• Hence, sonic_platform package installation has failed due to missing package wheel location with device path directory.

• Deinit and reinit the platform initialization script installs python package.
• But "config reload" didnot resolve the issue.

Steps to reproduce the issue:

1. Load latest master.
2. Run "sfputil" command and observe "No sonic_platform module error".

Describe the results you received:
