************* Module fract4d.gradient
fract4d/gradient.py:223:45: E0606: Possibly using variable 'factor' before assignment (possibly-used-before-assignment)
************* Module fract4d.tests.test_fract4d
fract4d/tests/test_fract4d.py:582:36: E0606: Possibly using variable 'temp' before assignment (possibly-used-before-assignment)
************* Module fract4d_compiler.translate
fract4d_compiler/translate.py:793:15: E0606: Possibly using variable 'r' before assignment (possibly-used-before-assignment)
