Error: Can’t initialize nvrm channel [How to Solve]

After the environment of Jetson nano is installed, debug the python program with Jupiter notebook. After starting
$Jupiter notebook
, a continuous prompt appears in terminal
error: can’t initialize nvrm channel
after query, it is related to the camera input on the nano, but the program does not use the camera. Jupyter can work normally, but it will affect the viewing of debugging information.

Solution:
to bypass this problem, open the chromium browser before starting jupyter, and then jupyter will open the page in the existing browser, so the above error will not appear in terminal.

[Solved] jetson nano Error: Illegal instruction(core dumped)

Jetson nano reported an error: legal instruction (core dumped)

Problem Description: it is not easy to replace the image source and configure the remote xrdp desktop for the Jetson nano development board (refer to my previous blog posts). When the project is deployed and running, the following errors do occur:

Illegal instruction(cpre dumped)

There is no way but to continue to check the data. The solution is as follows:

1. Terminal operation

sudo gedit ~/.bashrc

2. Add environment variables at the end, save and close the file

export OPENBLAS_CORETYPE=ARMV8

3. The terminal runs source ~/bashrc

run in the terminal: source ~/.bashrc

I restart it and then I can. Some blogs say that it is related to dependent packages in the environment

Ubuntu has solved the error of h5py installation: building wheel for h5py（ setup.py ）… or error: failed building wheel for h5py

introduction
Jetson nano
system: ubuntu 18.04 LTS

problem description

trying to install h5py:install PIP h5py times wrong.

through the Error log, and finding a “billion” pile of warning, the writer has focused on the right failing for the Cython : the Error compiling Cython file

was found after the study. Cython is not actually installed. This means that when we install H5PY using Pip3 Install H5PY, the installation program will download a temporary copy of Cython that may be experiencing compatibility problems with H5PY. So install Cython before PIP install h5py, and then install h5py :

install pip Cython

install pip h5py

successfully installed
