Question: I am trying to generate a word cloud using the WordCloud module in Python, however I see the following error whenever I call .generate Traceback (most recent call last): File "/mnt/6db3226b-5f96-4257-980d-bb8ec1dad8e7/test.py", line 4, in <module> wc.generate("foo bar foo bar hello world") File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 639, in generate return self.generate_from_text(text) File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 621, in generate_from_text self.generate_from_frequencies(words) File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 453, in generate_from_frequencies self.generate_from_frequencies(dict(frequencies[:2]), File "/home/mjc/.local/lib/python3.10/site-packages/wordcloud/wordcloud.py", line 508, in generate_from_frequencies box_size = draw.textbbox((0, 0), word, font=transposed_font, anchor="lt") File "/usr/lib/python3/dist-packages/PIL/ImageDraw.py", line 671, in textbbox raise ValueError("Only supported for TrueType fonts") ValueError: Only supported for TrueType fonts  As it stands, I am trying to create a very simple example WordCloud import matplotlib.pyplot as plt from wordcloud import WordCloud wc = WordCloud(background_color="white", font_path="./arial.ttf", width=800, height=400) wc.generate("foo bar foo bar hello world") plt.axis("off") plt.imshow(wc) plt.savefig("test.png") plt.show()  Where arial.ttf is downloaded from https://www.freefontspro.com/14454/arial.ttf and placed in the same directory as test.py. I am using Ubuntu 22.04 and Python 3.10.6. I was expecting to generate a word cloud from the input "foo bar foo bar hello world", however see the error ValueError: Only supported for TrueType fonts despite passing a ttf to the font_path argument.

Answer: I could not reproduce your error with Python 3.10 even after downloading the same font - though I am on macOS. The only thing I can imagine is that your PIL doesn't support TrueType fonts, so you can check with: python3 -m PIL  Sample Output --------------------------------------------------------------------

interested in "freetype" lines: python3 -m PIL | grep -i type  Then you may need to install freetype with a command something like - not too sure of the exact package name: sudo apt install
