''tutorial-opt': command not found' during test

[xiangzho72]

Hello,

Firstly thanks very much for the tutorial which is very informative for ones who has little knowledge on LLVM.

I'm following charters one by one, and in the section 3'writing first pass', I met with problem in the test using command 'bazel test tests:all" : ' //tests:ctlz.mlir.test PASSED in 0.4s //tests:ctlz_runner.mlir.test PASSED in 0.9s //tests:ctlz_simple.mlir.test PASSED in 0.4s //tests:affine_loop_unroll.mlir.test FAILED in 0.3s /home/user/.cache/bazel/_bazel_user/0d9e230fafe092ac5e7f4f9c63722bf8/execroot/_main/bazel-out/k8-fastbuild/testlogs/tests/affine_loop_unroll.mlir.test/test.log //tests:mul_to_add.mlir.test FAILED in 0.3s /home/user/.cache/bazel/_bazel_user/0d9e230fafe092ac5e7f4f9c63722bf8/execroot/_main/bazel-out/k8-fastbuild/testlogs/tests/mul_to_add.mlir.test/test.log'

The issue is that '

.---command stderr------------

| 'tutorial-opt': command not found

`-----------------------------

error: command failed with exit status: 127

' However, I could use 'bazel run tools:tutorial-opt -- -affine-full-unroll ${PWD}/tests/affine_loop_unroll.mlir' to run this test successfully.

I checked the directory tree for bazel-bin/tests/affine_loop_unroll.mlir.test.runfiles/, it doesn't have '/mlir_tutorial/' as suggested in lit.cfg.py. And here are the output when I enable commented code in lit.cfg.py. I'm on Ubuntu 20.04, can you please help me to check what could be wrong in my setup ？
