TypeError: __init__() got an unexpected keyword argument 'encoding'

[huckl3b3rry87]

I followed the tutorial on setting up AIRsim for URDFSim and I am able to spawn the URDF

Now I am trying to control it, using the documentation here and here, but alas, I am having issues.

I think that it is due to my need to make the PythonClient into a project that is visible by my main project. For instance looking at URDFsim in VS, there are 13 projects

But, when I look at my project, again setup using the instructions in the tutorial video, I only have 3 projects and the PythonClient is missing.

If you look at the folder structure of this, you can see that I copied the PythonClient folder from URDFsim into my project

Is there way to make it recognize PythonClient here so that it as a startup project?

Thank you!

[mitchellspryn]

For the sake of your sanity, I would recommend having two different VS solutions - one for the python client, one for UrdfSim. Start UrdfSim in one VS instance. Click play in unreal. Then, start your python solution. It should connect.

Be sure to give the window inside Unreal focus. Otherwise, it will run really slowly.

[huckl3b3rry87]

Sorry for the delay, I had to get Anaconda setup with VS.

Q1: is there an easy way to do this:

Be sure to give the window inside Unreal focus. Otherwise, it will run really slowly.

Unfortunately, I am still running into an issue. Here are my steps:

1) open my main project with an instance of VS 2) right click on the .uproject and open with Unreal Q2: Is this needed or can I open the project from the File Explorer?

3) open a second instance of VS which is the PythonClient project 4) right click on ArmClientTest.py and select Set as Startup File 5) right click on PythonClient and select Set as Startup Project 6) click play in Unreal 8) click on the PythonClient solution 7) click the green play button

Then I get an error as

specifically,

  Message=__init__() got an unexpected keyword argument 'encoding'
  Source=C:\users\admin\documents\workspace\udds_urdf\b\pythonclient\msgpack\_packer.pyx

    client = ArmClient.ArmClient()
  File "C:\Users\admin\Documents\workspace\UDDS_URDF\B\PythonClient\urdfbot\ArmClientTest.py", line 45, in <module>
    main()

So there seems to be a connection issue.

Please let me know if I am doing anything wrong or not needed, thanks!

[huckl3b3rry87]

also, my AirSim settings, located in ~/Documents/AirSim/ are copied from here, except for the URDF path, which I fixed.

Additionally, I added

"RpcEnabled": true,
"LocalHostIp": "127.0.0.1",

as per this AirSim issue

but still no luck

[mitchellspryn]

Q1: Yes. Click on the viewport. That will give focus to Unreal.

Q2: I think you can just double-click on the .uproj.

That's not a connection error, it looks like something's wrong with your install of msgpack or python. What versions do you have installed? Did you install msgpack-rpc-python? Can you expand the "Python Environments" tab?

[huckl3b3rry87]

Thank you very much for the fast response!

could not seem to expand this window, here are the others

I think that I am using Anaconda 5.2.0

msgpack-python                     0.5.6
msgpack-rpc-python                 0.4.1

here are some more details

Hmm. This is odd. I just tried it on my end using the versions of packages that you have installed, and everything works.

strange, when I look at the packages in the Solution explorer, it seems to be missing some

msgpack                            1.0.0
msgpack-numpy                      0.4.3.2
msgpack-rpc-python                 0.4.1

unless they are contained in something else

in the Anaconda 5.2.0 interactive window in VS

>>> import msgpackrpc
>>> msgpackrpc.__version__
'0.4.1'

[mitchellspryn]

Oh. That's actually a good catch. That means that the environment that VS is using is different from the one you're inspecting.

I notice that you have 2 anacondas installed. Could you be using the wrong one? What happens if you select the other one?

Probably not relevant, but I am on conda 4.8.3 instead of 4.5.4.

The nuclear solution is to go into the file having the error (C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\lib\site-packages\msgpackrpc\transport\tcp.py), and remove the "encodings" kwarg, but I'm not sure if that'd have other problems.

[huckl3b3rry87]

First I installed anaconda directly on windows, then I realized I could add it to my VS build, which I did and that is the one I think that I am using

If I switch to the one on my machine

Then I have to start installing some missing packages, which I did on the anaconda version that I added directly to my VS

[huckl3b3rry87]

for reference, I had to install

pip install msgpack
pip install msgpack-rpc-python
pip install keyboard
pip install jsonpickle

but I did not try it on the Anaconda that I first installed just with Windows

[mitchellspryn]

I see.

What happens if you run this code? Do you get a traceback?

import msgpack
p = msgpack.Packer(encoding='UTF-8', default=lambda x: x.to_msgpack())

[huckl3b3rry87]

[mitchellspryn]

Ok, great. It runs fine for me. Progress.

What is in C:\ProgramData\Anaconda3\Lib\site-packages\msgpack_version.py? (might be C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\lib\site-packages\msgpack_version.py for you)? I have this:

version = (0, 5, 6)

[mitchellspryn]

I think I see the problem. Can you uninstall msgpack, msgpack-python, msgpack-rpc-python, and msgpack-numpy. Then, reinstall msgpack-python and msgpack-rpc-python, leaving out msgpack and msgpack-numpy?

Then try running that snippet above. Hopefully, it should run without error.

[huckl3b3rry87]

I should have mentioned that, yeah I had to add msgpack to install msgpack-python I just did what you said and started to add the packages and got

PS C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64> pip install msgpack-python

[mitchellspryn]

Odd. What happens if you just remove msgpack?

[huckl3b3rry87]

I guess it installed, it just gave this red issue

distributed 1.21.8 requires msgpack, which is not installed.

so, last time, I installed msgpack

Currently I don't have msgpack. Maybe it will work?

[mitchellspryn]

This is strange. I nuked it from my system and installed, and I didn't get any warnings. Try the snippet above and see if it imports correctly and runs without error.

[huckl3b3rry87]

works!

Anaconda 5.2.0 interactive window [PTVS 15.9.18254.1-15.0]
Type $help for a list of commands.
>>> import msgpack
>>> p = msgpack.Packer(encoding='UTF-8', default=lambda x: x.to_msgpack())
>>> 

So, during installation, make sure not to install msgpack

Just install

msgpack-python
msgpack-rpc-python
pip install keyboard
pip install jsonpickle

[huckl3b3rry87]

And!! The URDF robot is moving around amazingly:)

Thank you so much @mitchellspryn !

[mitchellspryn]

Great. Glad we could get it up and running.

[huckl3b3rry87]

same:)
