I opened my notebook and started the first cell. It took about 2-4 minutes to set up the environment.
After that, I tried to install geopy via pip. The installation process started and lasted an unusually long time until it fell with exceeding available memory error. The computation restarted automatically and did not finish in 5–7 min. So I tried to restart the computation manually, reload the page, restart the browser, but the kernel did not set up in the usual time. After 10–15 min, the kernel started successfully.
I raise this problem because yesterday the environment started in a few seconds, but today and several days ago I had this problem.
