Apollo: can not connect to http://localhost:8887/

[PikachuHy]

I do as follow

bash docker/scripts/install_docker.sh
docker ps  
bash docker/scripts/dev_start.sh
bash docker/scripts/dev_into.sh
bash scripts/hmi.sh

and then

...
[WARNING] Failed to find device with pattern "ttyUSB*" ...
...
[WARNING] Failed to find device with pattern "ram*" ...
...
...
Start roscore...
HMI ros node service running at localhost:8887
HMI running at http://localhost:8887

but I can not connect to can not connect to http://localhost:8887/

[ycool]

It seems you miss a step: bash apollo.sh build

bash docker/scripts/install_docker.sh
docker ps
bash docker/scripts/dev_start.sh
bash docker/scripts/dev_into.sh

bash apollo.sh build
bash scripts/hmi.sh

[s7ev3n]

@ycool I have the same issue, and I dont miss the "bash apollo.sh build", which says [OK] Build passed!
and when I typed bash scripts/hmi.sh, there is no warning, just
Start roscore... HMI ros node service running at localhost:8887 HMI running at http://localhost:8887
And I cannot connect to http://localhost:8887/
Thanks in advance!

[startcode]

@s7ev3n can you share your log here by this command:
cat data/log/*
Thank you.

[zhiwango]

I also have the same problem as @s7ev3n

@wz18 @s7ev3n Can you try to install the missing packages with the following commands, and see if it solves the problem

#inside dev docker
 sudo apt-get install python-gevent
 sudo pip install grpcio
 sudo pip install -r modules/tools/py27_requirements.txt

It looks like a bug, and we will fix it soon.
Thank you for reporting this problem.

[zhiwango]

@startcode Thank you for your help, it has worked.

[startcode]

The build docker env is updated.
Please try the following commands again

bash docker/scripts/dev_start.sh #pull latest build docker env.
bash docker/scripts/dev_into.sh
bash apollo.sh build
bash scripts/hmi.sh

Thank you.

[yangyifeng01]

oh, I missed bash apollo.sh build too

[s7ev3n]

@startcode I tried to pull the lasted code and run the scripts, and the cat data/log/* shows:

smartcar@in_dev_docker:/apollo$ bash scripts/hmi.sh

It seems that it misses gflags, I will try install one.

[startcode]

@s7ev3n can you install python-gflags by the following command and try again?

sudo pip install python-gflags

Thank you.

[s7ev3n]

@startcode I try to install using sudo pip install python-gflags inside in_dev_docker, and it was actually already installed, unfortunately it still reported gflags missing. I am new to docker, is it the sudo pip install python-gflags install in docker container or in local computer?

[ycool]

@s7ev3n can you run the following command to update dev docker image?

$ bash docker/scripts/dev_start.sh #pull latest dev docker image

$ docker images 
# double check the dev docker image version
# apolloauto/apollo   dev-latest              6a0a38d980e3

Thanks.

[s7ev3n]

I updated dev docker image, it give a warning[WARNING] Failed to find device with pattern "ram*" ... .
Yes, I am pretty sure the dev docker image ID is 6a0a38d980e3.

[startcode]

@s7ev3n can you show your $PYTHONPATH inside dev docker by command:
echo $PYTHONPATH
Thank you.

[s7ev3n]

@startcode /apollo/bazel-genfiles:/apollo/bazel-apollo/external/ros/lib/python2.7/dist-packages:/apollo/third_party/ros_x86_64/lib/python2.7/dist-packages

[startcode]

Feels like an environment issue. I created one dev docker env from fresh, and the

$PYTHONPATH=/apollo/bazel-genfiles:/apollo/bazel-apollo/external/ros/lib/python2.7/dist-packages

I suggest you try to exit Docker first,
run

bash apollo.sh clean #to clean the generated files
rm -rf data third_party/ros third_party/ros_* # clean history ros files

Then run the following commands to start docker -> enter docker -> build

bash docker/scripts/dev_start.sh
bash docker/scripts/dev_into.sh
bash apollo.sh build
bash scripts/hmi.sh

[s7ev3n]

@startcode Thanks so much. However, the problem is still the same, now PYTHONPATH is /apollo/bazel-genfiles:/apollo/bazel-apollo/external/ros/lib/python2.7/dist-packages, and the cat data/log/* still shows ImportError: No module named gflags, and python-gflags is installed.

[startcode]

@s7ev3n Sorry that did not work out. thanks for your patience. We will keep investigating this issue.

[qiankunzhu]

Could you try pip list | grep gflags in the dev docker and show the info?
Or you can try clean and build again as the upper said: ./apollo.sh clean, ./apollo.sh build . To get more clear logs, you can remove the logs in data/log/ first.
Or stop and start the docker again with: docker stop $(docker ps -q) in host machine(out of docker terminal), and start with the readme guide. Hope to help u.

[startcode]

@s7ev3n
If you pull the latest code, you can run the following command to get your environment

bash scripts/env.sh >& env.txt

It will help us a lot if you can share the contents of env.txt.
Thank you.

[s7ev3n]

@startcode I installed release, and it successfully opened HMI on localhost:8887!
Here is the env.txt:

[startcode]

@s7ev3n You said " it successfully opened HMI on localhost:8887!", is your problem solved?
If so, I will close the issue.

[s7ev3n]

@startcode I uninstall gflags and reinstall it, it passed missing gflag error, but when still couldnt work.
I looked into the log, it seems missing many packages, and I install one by one: google.apputils, Flask-RESTful, Flask-SocketIO, glog, and I stuck here:

Import grpc:No module named coros
Traceback (most recent call last):
  File "modules/hmi/web/hmi_main.py", line 23, in <module>

    from grpc.beta import implementations as beta_implementations
ImportError: No module named beta

[s7ev3n]

@startcode I successfully opened HMI on release docker not on dev docker.

[startcode]

@s7ev3n Now you come across the same problem we addressed before in this thread. The following commands may work.

#inside dev docker
 sudo apt-get install python-gevent
 sudo pip install grpcio
 sudo pip install -r modules/tools/py27_requirements.txt

[s7ev3n]

@startcode I tried to install what you said, but the import error is still the same...what is this coros? How can I install it?

[s7ev3n]

I reinstalled grpcio, and it worked! Thanks so much ,you can close this issue now!

[startcode]

@s7ev3n Thank you for your patience, and thanks for your help of improving Apollo.
