我认为我在不同的Python版本之间发生了冲突。这是新的安装Ubuntu 18.04。除了来的那个，我没有安装任何其他Python。我安装了 anaconda ，并指定了版本 3.7 。
(pcntorch) mk@mk-ub:~/PCN-PyTorch$ python --version
Python 3.7.13
(pcntorch) mk@mk-ub:~/PCN-PyTorch$ conda deactivate
mk@mk-ub:~/PCN-PyTorch$ python --version
Python 2.7.17
我已经通过Conda安装了所有必要的要求和库。运行 render_depth.py 错误。
blender -b -P render/render_depth.py 'ycb_cad_models_specific' 'obj_list.txt' 'outputdir' 8
Traceback (most recent call last):
File "/home/mk/PCN-PyTorch/render/render_depth.py", line 27, in <module>
import numpy as np
ModuleNotFoundError: No module named 'numpy'
Error: File format is not supported in file '/home/mk/PCN-PyTorch/ycb_cad_models_specific'
运行以下命令时：
python -mpip install numpy
Requirement already satisfied: numpy in /home/mk/anaconda3/envs/pcntorch/lib/python3.7/site-packages (1.21.6)
在几个[问题]中> 2 ，，一个人对我的问题更具体，但没有帮助，我已经看到有时候解决方案是卸载Anaconda并再次安装。但是，由于我在康达（Conda）安装了一些库，我宁愿不这样做，例如，我遇到了同样的问题：
(pcntorch) mk@mk-ub:~/PCN-PyTorch/render$ python3 process_exr.py obj_list.txt ../outputdir/ 8
Traceback (most recent call last):
File "process_exr.py", line 25, in <module>
import Imath
ModuleNotFoundError: No module named 'Imath'
(pcntorch) mk@mk-ub:~/PCN-PyTorch/render$ python -mpip install imath
Requirement already satisfied: imath in /home/mk/anaconda3/envs/pcntorch/lib/python3.7/site-packages (0.0.1)
我的猜测是，道路在内部不匹配，但我很笨拙。 code

I think I am having conflict between different python versions. This is a fresh installed Ubuntu 18.04. I did not install any python other than the one that came. I installed anaconda, and specified the version 3.7.
(pcntorch) mk@mk-ub:~/PCN-PyTorch$ python --version
Python 3.7.13
(pcntorch) mk@mk-ub:~/PCN-PyTorch$ conda deactivate
mk@mk-ub:~/PCN-PyTorch$ python --version
Python 2.7.17
I already installed all the necessary requirements and libraries through conda. When running render_depth.py, I get the following error.
blender -b -P render/render_depth.py 'ycb_cad_models_specific' 'obj_list.txt' 'outputdir' 8
Traceback (most recent call last):
File "/home/mk/PCN-PyTorch/render/render_depth.py", line 27, in <module>

ModuleNotFoundError: No module named 'numpy'

When running the following command:
python -mpip install numpy

In several [questions] 2, numpy is installed but astropy says numpy is not installed, and this one was more specific to my problem but didn't help , I have seen that sometimes the solution is to uninstall anaconda and install it again. But I would prefer not do to so at the moment due to some libraries I installed in conda, imath for example, and I get the same issue:
(pcntorch) mk@mk-ub:~/PCN-PyTorch/render$ python3 process_exr.py obj_list.txt ../outputdir/ 8
Traceback (most recent call last):
File "process_exr.py", line 25, in <module>
import Imath
ModuleNotFoundError: No module named 'Imath'
(pcntorch) mk@mk-ub:~/PCN-PyTorch/render$ python -mpip install imath
Requirement already satisfied: imath in /home/mk/anaconda3/envs/pcntorch/lib/python3.7/site-packages (0.0.1)
My guess is that somehow the paths are not matching internally, but I am quite clueless...
