plot_metadata: X11 connection rejected because of wrong authentication / Cannot load backend 'TkAgg' which requires the 'tk' interactive framework, as 'headless' is currently running

[strawberry098]

I'm getting an error with plot_metadata

import tkinter as tk
import matplotlib
i = 0
while i < 10:
    i += 1
    try:
        matplotlib.use('TkAgg')
        break
    except:
        print(i)
from pycisTopic.clust_vis import (
    find_clusters,
    run_umap,
    run_tsne,
    plot_metadata,
    plot_topic,
    cell_topic_heatmap
)

plot_metadata(
    cistopic_obj1_models,
    reduction_name='UMAP',
    variables='predicted.id.from.act',
    target='cell', 
    text_size=10,
    dot_size=5)

Login you your server with ssh -X.

Or don't use import tkinter as tk and matplotlib.use('TkAgg')

import matplotlib

matplotlib.use('Agg')

import matplotlib.pyplot as plt
