While running full SLAM, loop closing is enabled by default and can be disabled by setting kUseLoopClosing=False in config_parameters.py. Different configuration options LoopDetectorConfigs can be found in loop_closing/loop_detector_configs.py: Code comments provide additional useful details. One can...
Using namedtupleincurs no extra runtime cost, and can make code much easier to read. The most common situation where a namedtuple is recommended is when a function returns multiple results, which are then unpacked into a tuple. Let’s look at an example of code that uses plain tuples, to...
DataLoader allows you to decouple unrelated parts of your application without sacrificing the performance of batch data-loading. While the loader presents an API that loads individual values, all concurrent requests will be coalesced and presented to your batch loading function. This allows your applica...
Compiled code, stack tracebacks (Part IV, Part VII) Table 4-1 isn’t really complete, because everything we process in Python programs is a kind of object. For instance, when we perform text pattern matching in Python, we create pattern objects, and when we perform network scripting, we...
Finally, the while loop executes the code in the body as long as the while condition is true. if-else # if-else statement x = 5 if x > 4 or x != 9: print("Output #124: {}".format(x)) else: print("Output #124: x is not greater than 4") This first example illustrates ...
Code up your solution. This is the fun part, which you’ll get a lot of practice for in the rest of this tutorial. Enter your answer to the puzzle on the puzzle page. If your answer is correct, then you earn a gold star, and part two of the puzzle opens up. Repeat steps 2 and...
The initial attempt to fix to this problem was to add markers in the instruction stream, initially this was aCOME_FROMinstruction, and then use that in pattern detection. Over the years, I've extended that to be more specific, soCOME_FROM_LOOPandCOME_FROM_WITHwere added. And I added chec...
We got rid of the loop and this makes things faster:</p> <pre class="code pycon literal-block"> <span class="keyword namespace"></span><span class="generic prompt">>>> </span><span class="keyword namespace">from</span> <span class="name namespace">tools</span>...
