When I do training, I get this error : AttributeError: 'FigureCanvasAgg' object has no attribute 'tostring_rgb'

you probably already seen this previous thread ? :
#2411
... but it tryed the solution given there... and it didn't work for me.
i'm still stuck.

matplotlib==3.7.0,
numpy==1.26.4

I had matplotlib 3.7.1 ==> installed 3.7.0 instead.
I had numpy 1.23.5 (It's the one indicated in the requirements.txt of the github page) ... so ==> i installed 1.26.4

Same result :(

After many, many tests... I finally fixed it in a very dumb way ;D
To explain... I tryed to install and run RVC, starting with this video here : https://youtu.be/nXpBlC6OBw4?si=5hef-vd-44dgbXFh
I did as he says.. clicked on the green Code button. copyed the url and "git clone" it ...ect...
and here started all my problems.

Then...one hour ago... i decided to try an other way that i saw in other videos.
I didn't use the Code button, but i clicked on the "Releases" link in the right column... then downloaded the Nvidia GPU package (as my Graphic card is an Nvidia).
And...
...
that's all.

Everything worked fine at first try.
what a waste of time.

was not a waste of time. you got it working, you learned something, and you shared it. thank you!

can you help me do that too ? i have the same problem .. i installed it using a one line code shown in https://www.youtube.com/watch?v=Y8IxVVQBEpc
and after a few minute of training i get AttributeError: 'FigureCanvasAgg' object has no attribute 'tostring_rgb'

i even tried downgrading matplotlib and numpy

I encourage you to try my method (as explained 2 messages above)... After spending days fighting with version conflicts, i installed what i think is the "standalone pack". It probably take more space on your hard-drive... but it worked at first try after :)

I hope it'll do for you too.

replac \infer\lib\train\utils.py, line 238, line 239 with these codes

data = np.frombuffer(fig.canvas.buffer_rgba(), dtype=np.uint8)
data = data.reshape((fig.canvas.get_width_height()[::-1] + (4,)))

add this code

data = data[..., :3]

plt.close()

it works for me (matplotlib=3.10.1, numpy=1.26.4)
