[gerroon]

HI

I installed it using pip on Windows 10 x64 Python37 . Then I fire ipython, then type "import bpy" this is what I got

: import bpy

ImportError Traceback (most recent call last)
in
----> 1 import bpy

ImportError: DLL load failed: The specified module could not be found

thanks

Hi there!

Thanks for filing the issue.

Could I get some more information about the environment that you are using this in? Namely:

• Are you using a venv?
• Is this some form of Iron Python? Iron Python is not supported. (you say ipython?)
• Could you please paste the entire stack trace of the crash? That would be very helpful.

Thanks in advance!

[gerroon]

Hi

I am not using venv, just installed it systemwide using pip3 install bpy

I am not using Iron Python. Ipython is part fo that Jupyter thing, Py console

Can you tell me how I get the stack trace of the crash on Windows?

thanks

[TylerGubala]

Sorry, I missed the fact that you gave me the import error. I'm away from my PC at the moment (on mobile).

I'm thinking that this is an issue I overlooked with my Python 3.7 builds.

I hope to complete this sometime this weekend.

Thanks for your patience.

[gerroon]

Thanks, let me know if you need testing

[micmelesse]

Is there any update one this. I am also using python 3.7 and did a system wide install using pip3 install bpy.

[TylerGubala]

Unfortunately I've been a bit busy with work lately, I have a fix in the works, but it may take a little while, as I am also chasing down Mac compatibility currently (just bought a used Mac to test).

Thanks for your patience.

I got this on 3.7, but I don't have hard dependency on Python version, so I decided to try with 3.5 and it still doesn't work. :(

Any workarounds?

[TylerGubala]

There's a fix in the pipeline, I've only recently got a small amout of time after work to investigate. In the meantime, Python 3.6 should work.

Hi, i have the same problem. The python I am using is python 3.4.3 and i did install it using a virtualenv. I also tried installing this a while back using Linux Mint but couldn't seem to get it work either. Is this incompatible with virtual environments?

[TylerGubala]

Currently, blenderpy only works for Python versions in the 3.6.x family, and only for Windows. I am working on the other builds, but due to work, have a very limited time to do so. If you have a PR for a fix for Linux, I would happily merge it. Let me kniw if you have any questions or further issues.

[caniko]

I get the same issue with 3.6.8

[TylerGubala]

@caniko2 Can you let me know what OS, platform (CPython I'm guessing?) Etc so that I can nail this down better? Should work for Windows CPython 3.6.x

[caniko]

Yes, CPython 3.6.x Windows 10

[caniko]

Does Blender support pypy or jpython?

[TylerGubala]

Blender might to some level, but this project targets neither of those environements currently.

[caniko]

After clean install, reverting back to Python 3.6 seems to solve the problem

[TylerGubala]

I cannot replicate the issue. Can someone please provide their complete steps to arrive at the issue point? I installed Python 3.6.8 32 and 64 bit on Windows and had 0 problems. I would like to fix this for whoever is having the issue but am struggling to replicate it.

3.6 worked for me, but we ran into issues where renders didn't match between running the same script via blender -b -y -P ... and using blender as python module, so we switched back to running via blender as that had correct renders.

[ashishgopal1414]

doesn't work for python 3.7.3 also :-(

[liwenssss]

is there any solution for python3.7.3?

[TylerGubala]

@liwenssss Try the sdist at test.pypi.org:

pip install --index-url https://test.pypi.org/simple/ bpy

Note: depending on your network connection it can take multiple hours to build from sdist.

[TylerGubala]

You should be able to pip install bpy && bpy_post_install on all platforms but linux now.

Python 3.7.x should work for all but Linux using bpy 2.82

[avishek-mondal]

Hi, when I ran

pip install bpy && bpy_post_install

I get the following error messages -

raceback (most recent call last):
  File "/usr/local/bin/bpy_post_install", line 11, in <module>
    sys.exit(post_install())
  File "/usr/local/lib/python3.7/site-packages/blenderpy/post_install.py", line 47, in post_install
    install_scripts_directory()

    +blender_scripts_search_root_dir)
blenderpy.BlenderScriptsDirUnknownError: Could not find Blender scripts directory in /usr/local/opt

Any idea how to solve this? I'm running on macOS 10.15.5
