Btw, I am able to isolate the code that causing the problem. It maybe easier for you to debug.

` import numpy as np
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
import seaborn as sns
from trains import Task

task = Task.init(project_name='examples', task_name='Matplotlib example')
x = [ 1,2,3]
y = [1,2,3]
x = list(x)
y = list(y)
f, ax = plt.subplots(figsize=(50, 0.7 * len(x)))
sns.barplot(y, x, orient="h", ax=ax)
plt.show() `
