Hi, Just double check it on Xavier with JetPack 4.5.1. matplotlib can be loaded without issue. nvidia@Xavier32G:~$ export DISPLAY=:0 nvidia@Xavier32G:~$ xhost + access control disabled, clients can connect from any host nvidia@Xavier32G:~$ source env36/bin/activate (env36) nvidia@Xavier32G:~$ python3 Python 3.6.9 (default, Oct 8 2020, 12:12:24) [GCC 8.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import matplotlib >>> Thanks.

Hi, Could you try it via apt-get? $ sudo apt-get install python3-matplotlib Thanks

When I try: $ sudo apt-get install python3-matplotlib It install matplotlib 2.1.1. and not in my virtual env but on host.

Hi, Could you try to enable the host package with the command in the following topic? [image] openCV import error on python virtual environment Jetson TX2 Hi, Please remember to enable the host side package to the virtual environment. $ virtualenv env --system-site-packages created virtual environment CPython3.6.9.final.0-64 in 433ms creator CPython3Posix(dest=/home/nvidia/env, clear=False, global=True) seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/home/nvidia/.local/share/virtualenv) added seed packages: pip==20.2.1, setuptools==49.2.1, wheel==0.34.2 activators BashActivator,CS… Thanks.

Tried : $ virtualenv env36 --system-site-packages Running virtualenv with interpreter /usr/bin/python2 New python executable in /home/nvidia/env36/bin/python2 Also creating executable in /home/nvidia/env36/bin/python Installing setuptools, pkg_resources, pip, wheel...done. But from venv it does not see: $ python3 Python 3.6.9 (default, Oct 8 2020, 12:12:24) [GCC 8.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import matplotlib Traceback (most recent call last): File " ", line 1, in ModuleNotFoundError: No module named 'matplotlib' Checked at host it works.

Hi, Have you installed it outside of the virtualenv first? Could you test if you can import the module correctly without using virtualenv? Thanks.

Hi, Yes, of course I checked outside matplotlib is installed and it works. I checked via python3 >>> import matplotlib And it’s ok
