HTTP Error 404: Not Found

[josephasmith97]

Hi there! I am new to Python and Ridgemap! It looks like a great tool which I would really like to start using but unfortunately I can't because I keep getting this error. What is going wrong here and how can I solve this issue? I am running python 3.8 on macOS catalina

I'm getting the same error. Same python 3.8 and same os! I was using this library without issue about 9 months ago and now the saved code that used to work won't run anymore.

Here's an example:

from ridge_map import RidgeMap RidgeMap().plot_map() Traceback (most recent call last): File "<pyshell#1>", line 1, in RidgeMap().plot_map() File "/Users/dcomposer/Library/Python/3.8/lib/python/site-packages/ridge_map/ridge_map.py", line 77, in init font = FontManager().prop File "/Users/dcomposer/Library/Python/3.8/lib/python/site-packages/ridge_map/ridge_map.py", line 51, in prop temp_file.write(urlopen(self.github_url).read()) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 222, in urlopen return opener.open(url, data, timeout) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 531, in open response = meth(req, response) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 640, in http_response response = self.parent.error( File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 569, in error return self._call_chain(args) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 502, in _call_chain result = func(args) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 649, in http_error_default raise HTTPError(req.full_url, code, msg, hdrs, fp) urllib.error.HTTPError: HTTP Error 404: Not Found

I had the same problem. I worked around it by doing: fm = FontManager(github_url="https://github.com/google/fonts/blob/master/ofl/cinzel/static/Cinzel-Regular.ttf?raw=true") RidgeMap(font=fm.prop).plot_map() Aparently the url changed from 'raw=True' to 'raw=true' in the end.

thanks for the fix! i confirmed it, and will merge it in.

@ColCarroll Thanks for this project work and for getting these fixes in for urllib. Would you be willing to cut a new release on PyPI that includes these fixes (so v0.0.3 it seems)? It would be great to have them up on there as at the moment one needs to install from GitHub HEAD to get things working:

Sure! I forgot this was on PyPI -- noticed https://github.com/scikit-hep/mplhep/issues/241, so maybe it won't be necessary, but should be quick to do, just in case!

Thanks. It happens! :)

noticed scikit-hep/mplhep#241, so maybe it won't be necessary, but should be quick to do, just in case!

Oh, my request for a new PyPI release was actually just out of my own interest in using ridge-map to make contour art of the river systems my wife does ecological research in. But ridge-map does keep on giving too with the nice FontManager you pointed out to me. :rocket:
