Description
Figure object created using "from matplotlib import figure" is not able to save figure.
Code for reproduction
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
from matplotlib import figure
def figure_bug(file):
fig = figure.Figure(figsize=(2,5), constrained_layout=True)
gs = gridspec.GridSpec(5, 1, figure=fig)
axs = [fig.add_subplot(gs[x]) for x in range(1, 5)]
fig.text(0.5, 0.5, file, fontsize=25)
fig.savefig(file)
plt.close(fig)
if __name__ == '__main__':
for i in range(0, 110):
file_name = f'{i}.png'
figure_bug(file_name)
print(f'Done {i}')
Actual outcome
