could not import redmax_py

[Navneet-Kaur21]

I have tried installing using the source and the docker method. (For both DiffHand and TactileSimulation)
I keep getting the same error again and again. Could you please help solving this?

Traceback (most recent call last):
File "test_sim_speed.py", line 13, in
import redmax_py as redmax
ModuleNotFoundError: No module named 'redmax_py'

Did you install DiffRedMax successfully (Step 4 in README instruction):

cd externals/DiffHand/core
python setup.py install

After you successfully install it, you should be able to import redmax_py in your conda environment.

Hi Jie Yes, I did. Here is the screenshot of the output after running the install command. [image: image.png]

I have followed the instructions in the README file. (docker and source both). In both the cases it gives the same error.

[eanswer]

That's strange. I just tried to install the codebase from scratch and it works for me. Right after you install redmax_py and open a python session in your command line, could you run import redmax_py?

[Navneet-Kaur21]

On running import redmax_py I get this:

[eanswer]

I see, could you check two things for me:

1. Which python path you are using, run below in terminal

which python

2. Check whether redmax_py is installed in your conda environment:

pip list | grep redmax-py

[eanswer]

May be also which pip

[Navneet-Kaur21]

1. /home/anaconda3/bin/python
2. returns nothing.
3. /home/anaconda3/bin/pip

[eanswer]

It seems that you are not in your conda env as shown in the python and pip path

[Navneet-Kaur21]

Okay. Here are the results in the env:

1. /home/navneetkaur/anaconda3/envs/tactile_control_env/bin/python
2. redmax-py 0.0.1
3. /home/navneetkaur/anaconda3/envs/tactile_control_env/bin/pip

[eanswer]

Then it seems you have installed redmax_py. Can you import it if you open a python via /home/navneetkaur/anaconda3/envs/tactile_control_env/bin/python

[Navneet-Kaur21]

Uhh no.

[eanswer]

that's so weird, I'm sorry that I have no other ideas about what went wrong...

[Navneet-Kaur21]

I tried it with a different pc. It is giving the same error. Could there be anything missing in the installation? Some prerequisites that I need before I can install it successfully?

[Runze-Zhao]

I have run into the same issue

[Navneet-Kaur21]

could you please let me know if you figure it out @Runze-Zhao

I have run into the same issue

[Navneet-Kaur21]

also, @eanswer could you share the folder - anaconda3/envs/tactile_control_env/lib/python3.8/site-packages/redmax_py-0.0.1-py3.8-linux-x86_64.egg or what files should it contain.

[Runze-Zhao]

could you please let me know if you figure it out @Runze-Zhao

I have run into the same issue

The problem on my side is that I don't recursively have to download all the folders under the project (DiffHand/pybind11),also lack of the package of libXxf86vm.After downloading the relevant files, re-run the setup.py and it will work fine.
I hope that helps.

[eanswer]

@Navneet-Kaur21 Let me know if the issue has been successfully solved by recursively cloning the project as mentioned by @Runze-Zhao so that I can close the issue.

Hello, I have run into the same issue. I cannot even install the 'redmax_py' pkg.

Hello, I have run into the same issue. I cannot even install the 'redmax_py' pkg.

I solve the problem by rebuilding the environment and now it works lol. Some packages must be missing when first time install the env.

[cidxb]

I ran into the same problem too.

First of all, i was using the docker image, since i got trouble by installation on
cd core python setup.py install
So i running it on the docker image instead.

And I after I got in the image, i used pip install -e . in the path /DiffHand/core/ .
I don't know if it is right practice, since if i not install it, I can't import it in the python environment or find

Then there will be
Preparing metadata (setup.py) ... done
Installing collected packages: redmax-py
Running setup.py develop for redmax-py
and

Installing collected packages: redmax-py
Running setup.py develop for redmax-py
Successfully installed redmax-py

Then if i enter python into the python command line,
i can successfully import redmax_py. But if I run the example script, the same old ModuleNotFoundError: No module named 'redmax_py' error will appear.
So i import os, use commend line path=os.path.abspath(redmax_py.__file__) print(path)
And it shows /workspace/DiffHand/core/redmax_py.cpython-37m-x86_64-linux-gnu.so

It this in order? So the solution maybe add this path into the package searching path or environment path?

Also I found that in the image, the package actually installed in the following path:

/usr/lib/python3.7/site-packages# ls
easy-install.pth  redmax_py-0.0.1-py3.7-linux-x86_64.egg

But the rest of the pip and the using python is from

/usr/bin/python
/usr/local/bin/pip
