Late at night, a user suddenly reached out for help, saying that the system on the 64G TF card of the Jetson Xavier NX development kit we provided suddenly could not access the graphical interface.
This user is a new user who just bought the NX development kit, and I can almost imagine their panic…
We have always emphasized that the NVIDIA Jetson development kits have been around for many years, and there are many users worldwide; the system is not fragile enough to fail at the slightest issue.
So I asked the user:
The user cooperatively explained the situation:
At this point, we could roughly determine a reason, so we asked a few more questions:
We also thank this user for honestly telling us what actions they took, which helped us analyze the cause and provide corresponding solutions. We have encountered a few users who only say: I did nothing and it just happened—this does not help in solving the problem.
So the truth emerged; if the user has manually installed it and installed it to the default path, we suggest to reflash the system directly. Because the dependencies of many built-in packages must have been broken.
This also serves as a reminder to developers; many developers like to chase the latest versions. If you must try, please install manually to a non-default path. This is similar to manually changing software versions on a desktop and then installing it to the default directory, which breaks the dependency relationships.
When suggesting manual installation, during the ./configure step, specify a specific user directory (i.e., ./configure –prefix=XXXX), and after installation, this will prevent conflicts with the system’s default Python version. In the future, when using pip, use the –user parameter, or search online for “how to install Python to a non-global directory” to maintain multiple versions of Python.
Additionally, it should be noted that for most software, the method of installing manually to a non-global default path is also a way to install software without root permissions. This is similar to choosing “install to Program Files” (requires admin rights, global) and “install for this user only (install to AppData\Roaming)” on Windows.
More Tips:
Promise me, you must install this little tool for NVIDIA Jetson!
If this habit is not developed, the development on the NVIDIA Jetson platform will be almost in vain…
