Hi everyone. I recently bought an Nvidia Jetson Nano Dev. Kit 2gb for my grad. project and I am a total newbie. After long hours I have managed to install opencv, tensorflow and keras to my board and when I test them in terminal by using python3 they work. I have also downloaded pycharm but when I create a new project, pycharm creates a virtual environment that doesn’t include any of modules that I have installed before. I tried to install these modules again by using pycharm but I have got bunch of errors. So is there a method that I can use them in a virtual environment or is there any other useful IDE that doesn’t require virtual environments?

Hi,

You will need to create the _virtualenv_ with `-system-site-packages` to enable the access of host modules.  
Please find more detail in the below topic:

Thanks.
