Python Plotly image how to save image to a iobuffer and read it back

Question

Python Matplotlib image is saved like :

img = io.BytesIO()
plt.savefig(img, format='png')
img.seek(0)
encoded = base64.b64encode(img.getvalue())

but for plotly image the same code showing error like:

AttributeError: 'Figure' object has no attribute 'figure'

Any solution for this?

Answer 1

io.BytesIO has a function write().

img = io.BytesIO()
fig_svg = fig.to_image(format="svg") # kaleido library
img.write(fig_svg)
img.seek(0)
