Using matplotlib

I’m trying to put a matplotlib plot in a markdown_card and it’s not working
my code:
filename = getfilename(filename=q.client.filename)
data = pd.read_csv(filename, delimiter=’,’)
plt.figure(figsize=(2, 2))
image_filename = f’{str(uuid.uuid4())}.png’
plt.savefig(_local_path + image_filename, format=‘png’)
image_path, = await[image_filename])
os.remove(_local_path + image_filename)['Home'] = ui.markdown_card(
			box='3 1 2 3',
			title='Correlation Plot',

the error is this ,and i think is in the upload command:

Forget this question i’ve detected the problem
