AttributeError: module 'taichi' has no attribute 'dynamics'

The problem occurs when I run the script under the /mls-cpic

Hi @guodewen , are you following this (https://taichi.readthedocs.io/en/latest/installation.html#ubuntu-arch-linux-and-mac-os-x) to install the legacy taichi? You might have used a version of taichi that is too new.

Hi, sir. I followed the instructions on the web page, and there is an error I don't know how to fix.

assert os.path.exists(os.path.join(bin_dir, 'libtaichi_core.dylib'))

AssertionError
Error: installation failed.

Then, I rerun the script

python3 install.py

And it occurs

Existing taichi installation detected.
Please remove existing taichi installation in

I have the same problem on a linux install... libtaichi_core is not being built apparently?

[yuanming-hu]

Hi guys,

Could you ls your taichi/build folder and share the results?

[MrBurnst]

... I don't get one - running the setup script does not generate a taichi build. and when I git pull the legacy branch I am unable to build it - I tried downgrading llvm to 8.0, python3.5 and 3.7, nothing works :/ last thing I got when building was

pybind11.h:1010:9: error: no matching function for call to 'operator delete'

in lib/python3.7/site-packages/taichi/lib I have
libdevice.10.bc libtaichi_core.so runtime_cuda.bc runtime_x86_64.bc taichi_core.so

• libtaichi_core.so points to taichi_core.so

CMakeCache.txt libccd.so libpartio.so Makefile
CMakeFiles libccd.so.2 libtaichi_core.so projects
