+## Notice (For melodic)
+The default Python version for Ubuntu-18.04 are as follows.
+```
+$ python --version
+Python 2.7.17
+
+$ python3 --version
+Python 3.6.9
+```
+This does not meet the `ultralytics` requirements and should be updated in the following steps.
+```
+$ sudo apt-get install -y python3.8
 
+$ sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
+update-alternatives: using /usr/bin/python3.8 to provide /usr/bin/python3 (python3) in auto mode
+
+$ python3 --version
+Python 3.8.0
+```
+Update `pip` with the following command just to be sure.
+```
+$ python3 -m pip install --upgrade pip
+```
+Then, you have to resolve the `ModuleNotFoundError` issue.
+```
+$ cd /usr/lib/python3/dist-packages
+$ sudo cp apt_pkg.cpython-36m-x86_64-linux-gnu.so apt_pkg.so
+$ sudo ln -s apt_pkg.cpython-{36m,38m}-x86_64-linux-gnu.so
+$ python3 -m pip install rospkg
+```
