@tom-gall please look into the CI failure

areusch · 2020-06-02T19:31:36Z

Hey Tom, to get this to build further along in the CI, I think you can add the following line to docs/conf.py:

'../tutorials/micro'

I added this around line 168 and it kept building

tutorials/micro/README.txt

@tom-gall please followup on @liangfu 's comment

Thanks @tom-gall for your valuable contribution on the uTVM tutorial. I've rendered your tutorial and it's not displayed correctly as expected. Please try generate the html by running

make html

in the <tvm_root>/docs directory, so that you could preview the rendered html (in <tvm_root>/docs/_build/html) and fix the syntax errors.

tutorials/micro/micro_tflite.py

+# install tflite
+# .. code-block:: bash
+#
+#   pip install tflite=2.1.0 --user


Please follow RST syntax to put the extra indentation, otherwise it's not rendered as code.

Please try reproduce the the rendered html by running

make html

in <tvm_root>/docs directory, so that the tutorial could be more reader friendly.

Interestingly make html dies with an exception :

I'm using ./tests/scripts/task_sphinx_precheck.sh which seems to generate less than perfect html when viewed elsewhere. I'm less than confident that the html generated is acceptable :-/

I was able to get this to work by deleting the other tutorials. I haven't seen that specific exception, though. I did build your tutorial locally and I think it looks okay now. i'll add a couple of small nitpicks which you could fix if you want to be a perfectionist about it.
