有一些可能的原因可能导致这种情况:

There are a few possible things that can be causing this:

1. 同一个python解释器?用import sys; print(sys.executable)
检查
2. 它是同一工作目录吗?用import os; print(os.getcwd())
检查
3. sys.path中的差异(python依次搜索导入位置的列表)可能是环境变量引起的.用import sys; print(sys.path)检查.

1. The same python interpreter? Check with import sys; print(sys.executable)
2. Is it the same working directory? Check with import os; print(os.getcwd())
3. Discrepancies in sys.path, which is the list python searches sequentially for import locations, can possibly caused by environment variables. Check with import sys; print(sys.path).
