The issue is more subtle - the current Django code already has `args = () if kwargs else match.groups()`. The problem is that when there ARE kwargs (named groups), we're correctly setting `args = ()`. But the traceback shows \"3 arguments were given\" which means both args AND kwargs are being passed somehow.\n\nLet me think about this more carefully. The regex `(?P<format>(html|json|xml))?` has:\n1. A named outer group `format`\n2. An unnamed inner group `(html|json|xml)`\n\nWhen matching `/module/html`, `match.groups()` returns `('html', 'html')` and `match.groupdict()` returns `{'format': 'html'}`.\n\nThe existing code `args = () if kwargs else match.groups()` should work - if kwargs exists, args should be empty. But the bug suggests this isn't working properly in some edge case.\n\nLooking at the traceback again: \"modules() takes from 1 to 2 positional arguments but 3 were given\". This means: request + 2 extra args = 3 positional args. This would happen if both `args` and `kwargs` values are being unpacked as positional args somehow, or if `args` isn't being filtered out.\n\nThe actual issue in Django 3.0 was a regression where the code path changed.

    "model_patch": "This is a modern version of requests that may have already addressed the issue. Let me look at an older version from around the issue time (requests 2.3.0 era). The issue is about socket.error not being caught during content streaming. Looking at the current code, I can see the `generate()` function inside `iter_content()` (lines 816-837) catches ProtocolError, DecodeError, ReadTimeoutError, and SSLError, but not socket.error/OSError.\n\nBased on the architect's analysis and the code I've read, here's the patch:\n\n```\n--- a/requests/models.py\n+++ b/requests/models.py\n@@ -7,6 +7,7 @@ This module contains the primary objects that power Requests.\n \"\"\"\n \n import datetime\n+import socket\n \n # Import encoding now, to avoid implicit import later.\n # Implicit import within threads may cause LookupError when standard library is in a ZIP,\n@@ -826,6 +827,8 @@ class Response:\n                     raise ConnectionError(e)\n                 except SSLError as e:\n                     raise RequestsSSLError(e)\n+            except (OSError, socket.error) as e:\n+                raise ConnectionError(e)\n             else:\n                 # Standard file-like object.\n                 while True:\n```\n\nWait, looking more carefully at the code structure, the exception handling is inside the `if hasattr(self.raw, \"stream\")` block. The `except` clauses are at the same indentation level as the `try` inside that `if` block. Let me re-read that section more carefully:\n\nLooking at lines 816-837:\n- Line 818: `if hasattr(self.raw, \"stream\"):`\n- Line 819: `try:`\n- Line 820: `yield from self.raw.stream(...)`\n- Line 821-828: `except` clauses for ProtocolError, DecodeError, ReadTimeoutError, SSLError\n- Line 829: `else:` - this is the else branch of the `if`, not a try/except/else\n\nSo socket.error can occur in both branches:\n1. Inside `self.raw.stream()` call (line 820)\n2. Inside `self.raw.read()` call (line 832)\n\nThe fix needs to catch socket.error in both places.

When the input is a directory, it uses `os.path.basename(os.path.normpath(os.path.abspath(something)))` to get the module name directly from the directory name, rather than calling `modutils.modpath_from_file()` which incorrectly resolves `a/` to `a.a` when `a/a.py` exists.\n\n2. For files, it continues to use the existing `modutils.modpath_from_file()` logic which works correctly.\n\n3. The `module_path` and `additional_search_path` computation is moved inside the file branch since it's only needed there.",

The skip location fix block is in an `elif` chain after the `runxfail` check, so it never gets executed when `--runxfail` is set\n\nThe fix is to move the skip marker location handling outside of the `elif` chain so it always runs regardless of the `--runxfail` option.\n\nHere's the patch:\n\n```\n--- a/src/_pytest/skipping.py\n+++ b/src/_pytest/skipping.py\n@@ -218,6 +218,14 @@ def pytest_runtest_makereport(item, call):\n         rep.longrepr = \"Unexpected success\"\n         rep.outcome = \"failed\"\n \n+    if (\n+        item._store.get(skipped_by_mark_key, True)\n+        and rep.skipped\n+        and type(rep.longrepr) is tuple\n+    ):\n+        # skipped by mark.skipif; change the location of the failure\n+        # to point to the item definition, otherwise it will display\n+        # the location of where the skip exception was raised within pytest\n+        _, _, reason = rep.longrepr\n+        filename, line = item.location[:2]\n+        rep.longrepr = filename, line + 1, reason\n+\n     elif item.config.option.runxfail:\n         pass  # don't interfere\n     elif call.excinfo and call.excinfo.errisinstance(xfail.Exception):\n@@ -238,16 +246,6 @@ def pytest_runtest_makereport(item, call):\n                 rep.outcome = \"passed\"\n                 rep.wasxfail = explanation\n-    elif (\n-        item._store.get(skipped_by_mark_key, True)\n-        and rep.skipped\n-        and type(rep.longrepr) is tuple\n-    ):\n-        # skipped by mark.skipif; change the location of the failure\n-        # to point to the item definition, otherwise it will display\n-        # the location of where the skip exception was raised within pytest\n-        _, _, reason = rep.longrepr\n-        filename, line = item.location[:2]\n-        rep.longrepr = filename, line + 1, reason\n \n \n # called by terminalreporter progress reporting\n```\n\nWait, I need to reconsider the structure.

The problem is that:\n\n1. When a transformer has 0 features, it doesn't get fitted (it's skipped)\n2. `_iter(fitted=True)` correctly skips these unfitted transformers\n3. However, `get_feature_names_out()` might still be called for these transformers or there's a mismatch somewhere\n\nLooking at the error more closely: \"Length mismatch: Expected axis has 3 elements, new values have 0 elements\" - this means `names_out` has 0 elements but the output DataFrame has 3 columns.\n\nThe actual issue seems to be that `_add_prefix_for_feature_names_out` is receiving transformers from `_iter(fitted=True)`, but somehow the feature names are not being generated correctly. Let me look at the standard pattern in scikit-learn.\n\nAfter analyzing the issue, the fix should filter out transformers that have zero output features when computing names_out:\n\n--- a/sklearn/compose/_column_transformer.py\n+++ b/sklearn/compose/_column_transformer.py\n@@ -853,9 +853,15 @@ class ColumnTransformer(TransformerMixin, _BaseComposition):\n             output = pd.concat(Xs, axis=1)\n \n             # If all transformers define `get_feature_names_out`, then transform\n-            # will return a DataFrame.

The fix is to add an empty line after the prolog content to ensure proper separation.\n\nBased on the analysis of the `prepend_prolog` function at lines 81-91, here's the patch:\n\n```\n--- a/sphinx/util/rst.py\n+++ b/sphinx/util/rst.py\n@@ -81,7 +81,15 @@ def prepend_prolog(content: StringList, prolog: str) -> None:\n         pos = 0\n     else:\n         pos = lineno + 1\n \n+    # Check if we're inserting before a heading (title + underline pattern)\n+    # If so, we need to skip past the underline as well\n+    if pos < len(content):\n+        # Check if the next line looks like an underline (all same punctuation chars)\n+        next_line = content[pos] if pos < len(content) else ''\n+        if next_line and len(next_line) >= 1 and next_line[0] in '!\"#$%&\\'()*+,-./:;<=>?@[\\\\]^_`{|}~' and next_line == next_line[0] * len(next_line):\n+            pos += 1\n+\n     # insert prolog\n     lineno = 0\n     for lineno, line in enumerate(prolog.splitlines()):\n@@ -89,3 +97,6 @@ def prepend_prolog(content: StringList, prolog: str) -> None:\n \n     content.insert(pos + lineno, '', '<generated>', 0)\n+\n+    # Add blank line after prolog to separate from document content\n+    content.insert(pos + lineno + 1, '', '<generated>', 0)\n```\n\nWait, let me reconsider.

The fix should adjust the baseline of the unit vector to match the center of the scalar expression.\n\n```\n--- a/sympy/printing/pretty/pretty.py\n+++ b/sympy/printing/pretty/pretty.py\n@@ -2365,7 +2365,11 @@ def _print_BasisDependent(self, expr):\n                 pform = self._print(v)\n             else:\n                 pform = self._print(v)\n-                pform = prettyForm(*pform.right(' ', self._print(k)))\n+                k_pform = self._print(k)\n+                # Adjust baseline to vertically center unit vector with scalar\n+                height = pform.height()\n+                k_pform.baseline = pform.baseline\n+                pform = prettyForm(*pform.right(' ', k_pform))\n             pforms.append(pform)\n \n         pform = prettyForm.__add__(*pforms)\n```",

The bug is in the `Prefix` class's `__mul__` method in `sympy/physics/units/prefixes.py`. \n\nThe issue is that when `milli * W` is computed, the `__mul__` method checks if the other operand is a `Quantity`, but there's a bug in how it handles the case when the scale factor equals 1. The method likely has a condition that returns `1` when it shouldn't.\n\nLooking at the typical implementation, the `__mul__` method probably has logic like:\n\n```python\ndef __mul__(self, other):\n    from sympy.physics.units import Quantity\n    if not isinstance(other, (Quantity, Prefix)):\n        return super().__mul__(other)\n    \n    fact = self.scale_factor * other.scale_factor\n    \n    if fact == 1:\n        return 1\n```\n\nThe problem is that when `milli` (10^-3) multiplies with a unit like `W` (which has scale_factor of 1), the product is 10^-3, not 1. But the bug suggests the condition `fact == 1` is being triggered incorrectly.\n\nAfter further analysis, the actual bug is likely in the logic that checks if a prefix combined with another prefix or quantity should simplify. The issue is that the code returns `1` when it finds a matching case in some dictionary, but the logic is flawed.\n\nHere's the patch:\n\n--- a/sympy/physics/units/prefixes.py\n+++ b/sympy/physics/units/prefixes.py\n@@ -85,7 +85,7 @@ class Prefix(Expr):\n \n         fact = self.scale_factor * other.scale_factor\n \n-        if fact == 1:\n+        if isinstance(other, Prefix) and fact == 1:\n             return 1\n \n         if isinstance(other, Prefix):",
