What is Travis ci test #35814.15 about? All other tests except this pass in my pr

I am traying to create a pr. But it fails the automatic testing by travis ci.

The test discription is :

TEST_ASCII="true" TEST_OPT_DEPENDENCY="numpy scipy gmpy2 matplotlib theano llvmlite autowrap cython wurlitzer python-symengine=0.3.* tensorflow numexpr ipython antlr-python-runtime>=4.7,<4.8 antlr>=4.7,<4.8 cloudpickle pyglet lfortran" TEST_SAGE="true"

This is for a pr in sympy. I tried to comare the job log of the test from a successful pull request and seems like my bin/test_travis.sh is not running.
