I often found that "spyder" was unstable and didn't start, but it seems that Spyder's instability is related to the Python version, the Tensorflow version, and the Spyder version. I have come to understand that. When I created a conda environment with python3.7 and installed Tensorflow-gpu = 1.15, spyder did not start. (Translated by Google Translate)
Spyder version or Anaconda version
File "C:\Users\Ovidio.spyder-py3\temp.py", line 26, in <module>
from tkinter import *
File "C:\Program Files\Spyder\pkgs\tkinter__init__.py", line 36, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: DLL load failed: No se puede encontrar el módulo especificado.
On the advice of
spyder-ide.org is used the 'Standalone Installer for macOS'.
This appears to be specific to macOS 10.15+ which I did not know. Spyder will not start and the Traceback mentions a frame "build for MacOS X 10.15". I only have macOS 10.13.
Two questions. (1) How can I uninstall this Spyder.app thoroughly? (2) Is there a better way to install - such as the standalone for 10.13?
