However, when I start the jupyter notebook and run !echo $PATH, I get /Users/$USER/anaconda3/bin. I might be missing something obvious in my installation, but I can't seem to figure out what it is. I am on OSX Sierra (10.12.5), and am using Jupyter Notebook v 4.3.0. From: Jason Grout python kernel install --user --name=venv, Changing the kernel.json path manually to the venv path does not fix the issue. It seems I am getting closer. I ran all analogous commands for Python2 as well. For now, you can probably work around it by changing the first item in argv to 'python3' in the Python 3 kernel.json file. However, I still got "Invalid Syntax" when I run "jupyter labextension install jupyterlab-drawio" or "install jupyterlab-drawio". When trying to run the kernel within a virtual environment, the system python (brew installed) is loaded instead. I also am experiencing this issue, and editing the two kernel.json files has solved the problem. You can also open a terminal and do a jupyter lab build.
