AttributeError: 'FigureCanvasAgg' object has no attribute 'tostring_rgb'

[Mehmet2407]

Whenever I press "train model" it goes up to 5.3 seconds and then says error on the progress bar. The command window shows this error in the last line. I have no idea what's wrong

i think this might be only related to tensorboard logs
if you don't need them you can just comment out the code or skip it

in infer/lib/train/utils.py find the summarize function and try catch it

def summarize(
    writer,
    global_step,
    scalars={},
    histograms={},
    images={},
    audios={},
    audio_sampling_rate=22050,
):
    try:
        for k, v in scalars.items():
            writer.add_scalar(k, v, global_step)
        for k, v in histograms.items():
            writer.add_histogram(k, v, global_step)
        for k, v in images.items():
            writer.add_image(k, v, global_step, dataformats="HWC")
        for k, v in audios.items():
            writer.add_audio(k, v, global_step, audio_sampling_rate)
    except Exception as e:
        print(f"Exception when summarizing  {e}. Skip, we don't care!")

pip install matplotlib==3.7.0,
It work for me

I also faced this error in the terminal window once training started. The workaround is downgrading matplotlib to 3.9 with: pip install matplotlib<3.10, likely due to breaking API changes with 3.10.
