     * attach USB cable to "device port." For USB the cable used matters. I had luck using usbc <--> usbc. Using usba <--> usbc failed
     * 1/2 way through the install process, sdkmanager will want to reconfirm/switch how host is communicating to the target. At this point the target is booted into the new OS
-    * at that point I switched to ethernet as both units were connected to my router. I'm not sure if sticking with usb might have worked

+==== Installing pyTorch ====
+//corrected from: [[https://docs.nvidia.com/deeplearning/frameworks/install-pytorch-jetson-platform/index.html]])//
+  * install ''jetpack''. (This is not the same as installing the OS for Jetson): ''sudo apt install nvidia-jetpack''
+  * get version of CUDA: ''nvcc --version''
+  * install ''cusparselt'':
+<code>
+wget raw.githubusercontent.com/pytorch/pytorch/5c6af2b583709f6176898c017424dc9981023c28/.ci/docker/common/install_cusparselt.sh
+sudo -s # set CUDA version and install as root
+export CUDA_VERSION=12.1 # as an example. Use the version returned from ''nvcc --version''
+bash ./install_cusparselt.sh
+</code>
+  * install correct numpy version: ''sudo pip install numpy==1.26.1''
+  * download correct version of pytorch for jetpack version. Search for it at [[https://developer.download.nvidia.cn/compute/redist/jp/]]
+<code>
+sudo pip3 install --no-cache http://<URL TO PYTORCH WHL>
+</code>
+==== misc ====
+  * [[https://elinux.org/Jetson_Zoo#ONNX_Runtime|onnxruntime for Jetson]]
+  * if ''onnxruntime'' fails with message ''Invalid argument. Specify the number of threads explicitly'' fix with one-time cli command: ''sudo nvpmodel -m 0'' which forces the computer to with no throttling
+  * ''tegrastats'' might show load on GPU?
+    * ''tegrastats | cut -f 14 -d " "'' shows % load on GPU
+  * you can get rid of the warning ''System Throttled due to Over-current'' by editing ''/usr/share/nvpmodel_indicator/nvpmodel_indicator.py''
