Error : Failed to find font DejaVu Sans

Hello every one I’ve encountered some diculites while I am running my function to display a - Scree Plot, and I get this error :

ValueError: Failed to find font DejaVu Sans:style=normal:variant=normal:weight=normal:stretch=normal:size=12.0, and fallback to the default font was disabled

My function is :

def display_scree_plot(pca):
‘’‘Display a scree plot for the pca’’’

scree = pca.explained_variance_ratio_*100
plt.bar(np.arange(len(scree))+1, scree)
plt.plot(np.arange(len(scree))+1, scree.cumsum(),c="red",marker='o')
plt.xlabel("Number of principal components")
plt.ylabel("Percentage explained variance")
plt.title("Scree plot")
plt.show(block=False)
