[英]“PortMidi: `Bad pointer'” when closing mido port
My code: 我的代码:
import mido
import time
mido.set_backend('mido.backends.pygame')
output = mido.open_output()
output.send(mido.Message('note_on', note=64, velocity=60))
time.sleep(3)
output.close()
After the last line, the following error is printed: 在最后一行之后,将打印以下错误:
Exception Exception: "PortMidi: `Bad pointer'" in <pypm.Output object at 0x025FF0B0> ignored
Apart from that, everything seems to work fine. 除此之外,一切似乎都很好。 However I'm developing a console app and this output is annoying.
但是我正在开发一个控制台应用程序,这个输出很烦人。 How can I get rid of this error?
我怎样才能摆脱这个错误?
