ModuleNotFoundError: No module named 'imp'
Backend QtAgg is interactive backend. Turning interactive mode on.
我的代码如下（原代码经过了处理，能触发这个Bug的代码如下）：
import torch
import matplotlib.pyplot as plt
def main():
data = torch.arange(1, 10)
plt.plot(data)
plt.title('label name')
# ……
if __name__ == '__main__':
main()
使用的时候 plt.ion() 不起作用。
这可能是由于 matplotlib 后端设置不正确。在我的代码中将 matplotlib 后端设置为“TkAgg”，这通常是最广泛支持的图形后端。
我在我的代码中尝试了这个并且成功了，这可能是由 vscode 错误引起的：
import matplotlib
matplotlib.use('TkAgg')
plt.ion()
总代码如下：
import torch
import matplotlib.pyplot as plt
import matplotlib
matplotlib.use('TkAgg')
plt.ion()
def main():
data = torch.arange(1, 10)
plt.plot(data)
plt.title('label name')
# ……
if __name__ == '__main__':
main()
