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

[TheTrustedComputer]

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.

[anurag12-webster]

same, downgrading to pip install matplotlib==3.7.0 worked for me,

[Charles-yueyue831]

pip install matplotlib==3.7.0, It work for me

I agree with you

[cahayamahardika16]

But you got this error thing was matplotlib this expired.

[meisei4]

I think this might be related? (https://github.com/matplotlib/matplotlib/pull/25484), I am not using this repos software, but i am using matplotlib version 3.10 and getting this error from trying to show plots in the jetbrains IDE PyCharm 2024.1.3 (Professional Edition, Runtime version: 17.0.11+1-b1207.24 x86_64, macOS 12.7.6) viewer:

Workaround is using matplotlib version 3.9.4 and below i think... (at least i tested with 3.9.4 and that solved my issue

[cahayamahardika16]

I got failure Preprocessing and Feature Extraction "AttributeError: 'NoneType' object has no attribute 'loader'"

[boycececil666gmailcom]

I am pretty sure the update of the matplotlib break its support with seaborn

[ikamensh]

someone should report this to matplotlib. I got this error while plotting generic data.

[FHeizenberg]

I had the same problem and the following helps me: `import matplotlib

matplotlib.use('TkAgg')` You can try to select another backend manually, here is the documentation https://matplotlib.org/stable/users/explain/figure/backends.html

[alobito]

Having the exact same issue. Downgrading matplotlib didn't help, no matter which version I tried.

[Bartabok]

same as alobito. I downgraded matplotlib with pip install matplotlib==3.7.0 as explained above.... but it solved nothing :/ Got same error message.

[GabrielDornelles]

it was removed on matplotlib 3.10. If you want to use downgrade to <3.10

[Joseph-Sherman]

can you help me? im not familiar with these kind of stuff .. just wanted to use RVC but get AttributeError: 'FigureCanvasAgg' object has no attribute 'tostring_rgb' . I tried and downgraded numpy and matplotlib .. but the issue persists

[Docteur-RS]

As of today (03/04/25) doing pip install matplotlib==3.7.0 fixed the error and got to the epoch part.

[EscoffierZhou]

Python in3.12.0,downgrading to pip install matplotlib==3.9.0works though in 3.7.0 seems still dysfunctional
