Can't connect ROMP into addon

[hasanleiva]

I use ROMP v1.1 on Windows machine.
But CDBA works with version 1.0 of ROMP
I read installation and using documentation of ROMP v1.0 but i can't figured out all
How can i use this addon properly?
I'm not good at programming i'm animator and interested in your project.
Can you write steps how to install and use ROMP with this addon,please?

Have you tried to install simple-romp?

Sorry, try Googling the error message, or ask the author of ROMP. I only used pip install --upgrade simple-romp to install ROMP, and I couldn't solve the problem.

i have same error ,have you done this error?

[yanchxx]

I guess it has something to do with your version of python. Can you provide more details? This includes python versions, pip versions, installed dependencies, etc.

The error message here is that lap cannot be installed, I suggest it is better to use the error message Google.

是的，的确是lap安装错误，我blender 2.9 python 3.7 安装错误，换成 blender 3.4 python 3.10 还是报错 ，我后来在anaconda 下安装同样版本的python，然后安装lap，之后将lap库拷贝到 blender 3.4 python的site-packages下， pip 一遍就可以了，我觉得是 blender python 环境管理的问题，有些依赖环境不全，安装起来总是报错，这么做的后果就是，我的cv用不了：ImportError: DLL load failed while importing cv2: 找不到指定的模块。 我还在解决这个错误

这是我的操作命令：

我在blender下面安装的 opencv库， 他不在我这个目录下 C:\Program Files\Blender Foundation\Blender 3.4\3.4\python\lib\site-packages，而是在C盘新建一个文件夹 C:\Users\A\AppData\Roaming\Python\Python310\site-packages，这是为什么

[zhanghongyong123456]

不使用blender 自带 python 环境，采用 anconda 创建的虚拟环境替代：

1. 找到 blender 自带python 环境 路径（默认：C:\Program Files\Blender Foundation\Blender 3.4\3.4\python\bin），查看 python 版本（3.10.8）；
2. 在anconda下创建新的虚拟环境： conda create -n blender3.4 python=3.10.8 （这里python 版本最好和 上面查看的版本名一致，其实不一致也是可以的）。
3. 修改 blender自带 python环境的文件夹（C:\Program Files\Blender Foundation\Blender 3.4\3.4），里面的python文件夹改名字，例如 __python,目的是防止blender 查找自带的python环境
4. 链接 自己在anconda下新建的虚拟环境的 blender3.4 ； 以管理员身份打开控制提示符：cd 到 blender自带 python环境的文件夹（C:\Program Files\Blender Foundation\Blender 3.4\3.4） 链接命令： Mklink /j python H:\Anaconda3\envs\blender3.4 ，这时blender 使用的pytho环境就是你新创建的虚拟环境。
   5.激活anconda下的虚拟环境 conda activate blender3.4， 此刻随意安装自己想安装的库。

simple_romp不需要安装在blender python里面，可以单独开一个conda环境

./python -m pip list 查看一下pip的已安装软件，看看有没有安装在里面。反正明确运行的python是blender的python，保证pip是属于blender python的pip就行，应该没啥问题。

不使用blender 自带 python 环境，采用 anconda 创建的虚拟环境替代：

1. 找到 blender 自带python 环境 路径（默认：C:\Program Files\Blender Foundation\Blender 3.4\3.4\python\bin），查看 python 版本（3.10.8）；

   5.激活anconda下的虚拟环境 conda activate blender3.4， 此刻随意安装自己想安装的库。

嗯，这是个不错的方案。

我readme没讲清楚，所以让你们以为simple_romp也安装在blender python里面了，如果是单独的conda环境的话，simple_romp应该是比较好安装的，只有opencv是需要安装在blender中的。

感谢你的反馈。

simple_romp is installed in a separate conda environment, only opencv needs to be installed in blender python. @hasanleiva

我想这与您的python版本有关。你能提供更多细节吗？这里包括python版本，pip版本，安装的依赖等
，这里的报错信息是无法安装lap，我建议还是用报错信息谷歌比较好。

是的，的确是lap安装错误，我blender 2.9 python 3.7 安装错误，换成 blender 3.4 python 3.10 还是报错 ，我后来在anaconda 下安装同样版本的python，然后安装lap，之后将lap库拷贝到 blender 3.4 python的site-packages下， pip 一遍就可以了，我觉得是 blender python 环境管理的问题，有些依赖环境不全，安装起来总是报错，这么做的后果就是，我的cv用不了：ImportError: DLL load failed while importing cv2: 找不到指定的模块。 我还在解决这个错误

simple_romp不需要安装在blender python里面，可以单独开一个conda环境

这是我的操作命令：

我在blender下面安装的 opencv库， 他不在我这个目录下 C:\Program Files\Blender Foundation\Blender 3.4\3.4\python\lib\site-packages，而是在C盘新建一个文件夹 C:\Users\A\AppData\Roaming\Python\Python310\site-packages，这是为什么

./python -m pip list 查看一下pip的已安装软件，看看有没有安装在里面。反正明确运行的python是blender的python，保证pip是属于blender python的pip就行，应该没啥问题。

不使用blender 自带 python 环境，采用 anconda 创建的虚拟环境替代：

1. 找到 blender 自带python 环境 路径（默认：C:\Program Files\Blender Foundation\Blender 3.4\3.4\python\bin），查看 python 版本（3.10.8）；
2. 在anconda下创建新的虚拟环境： conda create -n blender3.4 python=3.10.8 （这里python 版本最好和 上面查看的版本名一致，其实不一致也是可以的）。
3. 修改 blender自带 python环境的文件夹（C:\Program Files\Blender Foundation\Blender 3.4\3.4），里面的python文件夹改名字，例如 __python,目的是防止blender 查找自带的python环境
4. 链接 自己在anconda下新建的虚拟环境的 blender3.4 ； 以管理员身份打开控制提示符：cd 到 blender自带 python环境的文件夹（C:\Program Files\Blender Foundation\Blender 3.4\3.4） 链接命令： Mklink /j python H:\Anaconda3\envs\blender3.4 ，这时blender 使用的pytho环境就是你新创建的虚拟环境。
   5.激活anconda下的虚拟环境 conda activate blender3.4， 此刻随意安装自己想安装的库。

嗯，这是个不错的方案。

我readme没讲清楚，所以让你们以为simple_romp也安装在blender python里面了，如果是单独的conda环境的话，simple_romp应该是比较好安装的，只有opencv是需要安装在blender中的。

感谢你的反馈。

我的这个操作直接把blender 自带的python环境替换了，不使用blender自带的环境，自己在anconda 新建一个虚拟环境替代了，所有库安装和使用与blender自带的python环境一点关系没有，后续在blender里面的运行环境也是新的虚拟环境，而非本身自带的环境。
