sudo apt-get install git cmake
$ sudo apt-get install libatlas-base-dev gfortran
$ sudo apt-get install libhdf5-serial-dev hdf5-tools
$ sudo apt-get install python3-dev
the last three fail…something to do with unmet requirements???
What error did you see?
Reading package lists… Done
Building dependency tree
Reading state information… Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
gfortran : Depends: gfortran-7 (>= 7.3.0-12~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I think the only error here is that you cannot install gfortran.
Why do you need it? Also, it seems the apt-get tries to install amd64 gfortran-7. Could you use command “dpkg --print-foreign-architectures” and share the result?
I am just trying to get anything to work on this Nano.
I am following these instructions that don’t work!
I just need a working Python demo that I can use to understand the Nano operation. I already use OpenCV and program in Python 3.7. Nano is supposed to be fast.
I use matplotlib and Numpy etc without problem.
Nano does not seem to have any help files or demo python starter files.
Oh and the response to that command was:

Hi web7ptya, it seems the response to the command didn’t get posted in your reply above.
However, I am able to install the gfortran package without issue on Nano - did you run ‘sudo apt-get update’ first? You might want to re-flash a fresh SD card image of JetPack if you continue to have issues with the packages.
Also, here are some other tutorials of DNN inferencing on Nano with Python:

Hi,
sudo apt-get update seemed to do the trick…
Many thanks,
