Python install problem

[SiyuanHuang95]

Hi,

thanks for the sharing.

After cmake and make, I could run the GUI with C++ version successfully, very impressive!

And then, I removed the build/ folder and tried to use

cd python/
pip install -e .

to install the python version, however, the process has already taken about 2 hrs, and I can only see something like " Running setup.py develop for mujoco-mpc" in the terminal, at the same time, I found that the build/ folder is growing at first and then stay consistently:

Every 5.0s: du --max-depth=1 -h                                                                 

1.5G    ./_deps
16K     ./mjpc
400K    ./CMakeFiles
8.0K    ./grpc
1.5G    .

Was that normal? Or is there anything wrong with my operation?

Or, is there any walk-around like docker or Py-PIP to obtain that python package?

[SiyuanHuang95]

After some hours waiting, it gives me:

Successfully installed mujoco-mpc-0.1.0

with the build folder:

288K    ./gens
615M    ./lib
520K    ./protos
3.1G    ./_deps
4.0K    ./http_archives
19M     ./mjpc
311M    ./bin
1.6M    ./CMakeFiles
16M     ./grpc
4.0G    .

however, when try

python ui_agent_test.py

error raises:

ModuleNotFoundError: No module named 'mujoco_mpc.proto'

Should I re-install it?

[SiyuanHuang95]

After many trail and errors, I finally successfully install it. Some lessons:

1. Do not use pip install -e, just use install, this will speed-up the process if you do not need to modify some source codes.
2. USE python>=3.10!

[SiyuanHuang95]

I have successfully run some test scripts:

1. python agent_test.py -> success
2. python ui_agent_test.py -> success
3. python estimator_test.py -> cannot import name 'estimator_pb2' from 'mujoco_mpc.proto' (/home/XXX/anaconda3/envs/mjpc/lib/python3.10/site-packages/mujoco_mpc/proto/init.py)

I install the packages with:

python setup.py install
python setup_estimator.py install

and both give me the success flag.

[SiyuanHuang95]

I also tried with

pip install PATH/mujoco_mpc/python

and the terminal gives me:

**byte-compiling build/bdist.linux-x86_64/egg/mujoco_mpc/proto/estimator_pb2.py to estimator_pb2.cpython-310.pyc**
**byte-compiling build/bdist.linux-x86_64/egg/mujoco_mpc/proto/agent_pb2.py to agent_pb2.cpython-310.pyc**
**byte-compiling build/bdist.linux-x86_64/egg/mujoco_mpc/proto/estimator_pb2_grpc.py to estimator_pb2_grpc.cpython-310.pyc**
...


Using /XX/anaconda3/envs/mjpc/lib/python3.10/site-packages
Finished processing dependencies for mujoco-mpc==0.1.0

So I thought the install process is successful?

But the python estimator_test.py -> cannot import name 'estimator_pb2' from 'mujoco_mpc.proto' (/home/XXX/anaconda3/envs/mjpc/lib/python3.10/site-packages/mujoco_mpc/proto/init.py)

Any help and information is indeed appreciate!

I do the following:

1. run python python/setup.py install from the mujoco_mpc directory
2. test that the install was successful with python python/mujoco_mpc/agent_test.py

If you still encounter issues, feel free to reach out via email to me and I can walk you through the install and using MJPC python in a colab notebook.

I do the following:

1. run python python/setup.py install from the mujoco_mpc directory
2. test that the install was successful with python python/mujoco_mpc/agent_test.py

Hi, @thowell, great thanks for your reply.

I can also test the installation successfully with python python/mujoco_mpc/agent_test.py, but no success for the * estimator_test.py*. The biggest problem is with the proto stuff used in the estimator.

[thowell]

#142 should fix this

[thowell]

Are you installing the estimator first: python python/setup_estimator.py install?

[SiyuanHuang95]

Are you installing the estimator first: python python/setup_estimator.py install?

Hi thanks for your reply @thowell

Nopes, I directly run with

pip install PATH/mujoco_mpc/python

will this make a big difference?

Update:

I also tried with

python setup.py install
python setup_estimator.py install

also no success with python estimator_test.py

[Hither1]

Is setup_estimator.py replaced by setup_batch.py in the latest version?

[thowell]

@SiyuanHuang95 the README is updated with improved installation instructions.
@Hither1 the latest filename is setup_direct.py.
