Fix ImportError: Python Module Import Resolution Failures

Sat, 18 Jul 2026 00:44:04 +0800

1. Symptoms

When Python encounters an ImportError during runtime, the interpreter terminates execution and displays a traceback that reveals the failure point. The error manifests in several distinct patterns depending on the root cause.

Module Not Found Scenario:

Traceback (most recent call last):
  File "main.py", line 3, in <module>
    import requests
ImportError: No module named 'requests'

Circular Import Scenario:

Traceback (most recent call last):
  File "module_a.py", line 2, in <module>
    import module_b
  File "module_b.py", line 3, in <module>
    import module_a
ImportError: cannot import name 'some_function' from partially initialized module 'module_a'

Relative Import Error:

Fix go-import-cycle-not-allowed: Resolve circular dependencies in Go package imports

Sun, 05 Jul 2026 17:51:00 +0800

The import cycle not allowed error is a common compilation issue in Go that indicates a circular dependency between packages. This means that Package A imports Package B, and Package B, in turn, imports Package A, either directly or through a chain of other packages. Go’s design explicitly forbids such cycles to ensure clear dependency graphs, predictable package initialization order, and to prevent potential infinite recursion during compilation. Resolving this error typically involves refactoring your code to break these circular relationships, often by introducing new, independent packages or reorganizing existing functionality.
