Root Cause

Passing a string instead of a boolean to plt.ion() or plt.ioff(), or setting rcParams['interactive'] to a string.

generic

中文

向plt.ion()或plt.ioff()传递了字符串而非布尔值，或将rcParams['interactive']设置为字符串。

Workarounds

  1. 95% success Use plt.ion() to enable interactive mode (no arguments) 
    plt.ion()
  2. 90% success Set rcParams with a boolean 
    plt.rcParams['interactive'] = True

Dead Ends

Common approaches that don't work:

  1. Using 1 or 0 instead of True/False 70% fail

    While 1 and 0 are truthy, they are not booleans; the function expects a bool.

  2. Setting plt.ion(True) with parentheses 90% fail

    plt.ion() takes no arguments; it toggles interactive mode on. Passing an argument raises TypeError.
