In turn Path utilizes super().__init__ for creating a new\r\ninstance. However, Path.__init__ and TextPath.__init__ are completely different.\n\n### Code for reproduction\n\n```python\nfrom matplotlib.textpath import TextPath\r\nTextPath((0, 0), \".\").deepcopy()\n```\n\n\n### Actual outcome\n\n```python\r\nAttributeError                            Traceback (most recent call last)\r\nc:\\figures.py in \u003cmodule\u003e\r\n----\u003e 1 TextPath((0, 0), \".\").deepcopy()\r\n\r\n~\\.site-packages\\matplotlib\\path.py in __deepcopy__(self, memo)\r\n    284         return self.__class__(\r\n    285             self.vertices.copy(), codes,\r\n--\u003e 286             _interpolation_steps=self._interpolation_steps)\r\n    287 \r\n    288     deepcopy = __deepcopy__\r\n\r\n~\\.site-packages\\matplotlib\\textpath.py in __init__(self, xy, s, size, prop, _interpolation_steps, usetex)\r\n    394 \r\n    395         self._cached_vertices = None\r\n--\u003e 396         s, ismath = Text(usetex=usetex)._preprocess_math(s)\r\n    397         self._vertices, self._codes = text_to_path.get_text_path(\r\n    398             prop, s, ismath=ismath)\r\n\r\n~\\.site-packages\\matplotlib\\text.py in _preprocess_math(self, s)\r\n   1186             return s, True\r\n   1187         else:\r\n-\u003e 1188             return s.replace(r\"\\$\", \"$\"), False\r\n   1189 \r\n   1190     def set_fontproperties(self, fp):\r\n\r\nAttributeError: 'list' object has no attribute 'replace'\r\n```\n\n### Expected outcome\n\nA new instance of TextPath.\n\n### Operating system\n\nWindows 10\n\n### Matplotlib Version\n\n3.3.4\n\n### Matplotlib Backend\n\nmodule://ipykernel.pylab.backend_inline\n\n### Python version\n\nPython 3.6.6\n\n### Jupyter version\n\n_No response_\n\n### Other libraries\n\n_No response_\n\n### Installation\n\npip\n\n### Conda channel\n\n_No response_","author":{"url":"https://github.com/deep-jkl","@type":"Person","name":"deep-jkl"},"datePublished":"2021-08-29T18:51:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/20943/matplotlib/issues/20943"}
