It sounds to me like your installation is messed up somehow. Also, the "no active environment" looks a bit suspicious.
To debug issues like this, I usually try to start python alone, import something relevant (like notebook), and then query `notebook.__file__` to see if I'm importing notebook from where I think I should be importing notebook: python -c "import notebook; print(notebook.__file__)" or something Jason On Thu, Oct 17, 2019 at 8:53 AM brian piercy <[email protected]> wrote: > > - rebuilding after a crash. i started via a fresh Anaconda download. > Here's the results of 'jupyter --version" > > > - bjpcjp@bjpcjp-Lenovo-Z710:~$ jupyter --version > - jupyter core : 4.6.0 > - jupyter-notebook : 6.0.1 > - qtconsole : 4.5.5 > - ipython : 7.8.0 > - ipykernel : 5.1.2 > - jupyter client : 5.3.4 > - jupyter lab : not installed ('conda install jupyterlab' returns "all > packages already installed") > - nbconvert : 5.6.0 > - ipywidgets : 7.5.1 > - nbformat : 4.4.0 > - traitlets : 4.3.3 > > > - I get the error msg shown in the title, despite multiple reinstalls, > via "jupyter notebook". > > according to 'conda info': > > - no active environment > - conda 4.7, conda-build 3.18, python 3.7.4. > - channel URLs listed > - package caches present; envs directories present; linux-64 platform. > > ideas?
