我正在嘗試運行一個腳本，該腳本呼叫另一個 python 檔案（連同其整個 github 存盤庫一起復制），但是ModuleNotFoundError:
盡管將檔案放入正確的目錄中，但我得到了一個 This is。
我如何運行它
- 激活我的python3.9虛擬環境
(newpy39) aevas@aevas-Precision-7560:~/Desktop/Dashboard_2021_12$ python3 dashboard.py其中 aevas 是我的用戶名，而 ~/Desktop/Dashboard_2021_12 是檔案夾
運行它不需要額外的引數。
儀表板.py 的匯入

sys.path.insert(1, 'targetTrack')

第 1 部分：未找到模型，盡管模型是父檔案夾。
python3 dashboard.py

ModuleNotFoundError: No module named 'models'
第 2 部分：將 import models.common 更改為 import common 后，即使在同一個檔案夾中也找不到 common ！
python3 dashboard.py

這就是檔案夾模型中檔案的樣子
這就是experimental.py 的匯入部分的樣子

我已經查閱了以下鏈接，但無濟于事：
- https://towardsdatascience.com/how-to-fix-modulenotfounderror-and-importerror-248ce5b69b1c
- Python can't find module in the same folder
- ModuleNotFoundError: No module named 'models'
- https://github.com/ultralytics/yolov5/issues/353
I understand that I can change it to import .common and then the module can be successfully imported. However, the next line import utils causes a similar error. utils is on the same level as models. Which means there is going to be a cascade of moduleNotFoundError errors at this rate. I also understand using the folder ()method is inadvisable, hence I did not continue with it.
As I had mentioned that I had copied the entire cloned github repo over, when executed standalone, the github repo works perfectly fine. There are no differences between the experimental.py.
What could be wrong?
uj5u.com熱心網友回復：
問題是models模塊位于/home/aevas/Desktop/Dashboard_2021_12/targetTrack/yolov5檔案夾中，但是當您從 運行 dashboard.py 時/home/aevas/Desktop/Dashboard_2021_12/，Python 解釋器不會在/home/aevas/Desktop/Dashboard_2021_12/targetTrack/yolov5檔案夾中查找模塊；它只在/home/aevas/Desktop/Dashboard_2021_12/.
解決此問題的常用方法是將 yolov5 安裝為一個包，但似乎 yolov5 不包含以這種方式安裝所需的代碼。要解決這個問題，您需要讓 Python 知道它需要在 yolov5 檔案夾中查找模塊。
快速而簡單的方法是將檔案夾添加到 PYTHONPATH 環境變數中。
在嘗試匯入模塊之前，將 yolov5 檔案夾動態添加到sys.path是一種稍微不那么快速和骯臟但仍然很丑陋的方法。models您可以通過在dashboard.py 的頂部添加如下內容來做到這一點：
from pathlib import Path
import sys
sys.path.append(str(Path(__file__, "..", "targetTrack", "yolov5").resolve()))
