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

[wang850228803]

I use ubutnu16.04.

I installed taichi using command:
python3 -m pip install taichi-nightly

And installing Taichi Library using command:

wget https://raw.githubusercontent.com/yuanming-hu/taichi/legacy/install.py
python3 install.py

And set the environment path:

export TAICHI_REPO_DIR=/home/wanghui/code/taichi-etc/taichi
export PYTHONPATH=TAICHI_REPO_DIR/python/:$PYTHONPATH

But when i run the example fractal.py:

[T 01/09/20 17:01:52.987] [logging.cpp:Logger@67] Taichi core started. Thread ID = 8648
Traceback (most recent call last):
  File "fractal.py", line 4, in <module>
    pixels = ti.var(dt=ti.f32, shape=(n * 2, n))
AttributeError: module 'taichi' has no attribute 'var'

Anything wrong?

Hi,

python3 -m pip install taichi-nightly is all you need.

Please remove your taichi repo and env variables - they will fight against pip.

Hi,

python3 -m pip install taichi-nightly is all you need.

Please remove your taichi repo and env variables - they will fight against pip.

export TAICHI_NUM_THREADS=8
export TAICHI_REPO_DIR=/Users/XXXX/Documents/Taichi/taichi
export PYTHONPATH=$TAICHI_REPO_DIR/python/:$PYTHONPATH
export PATH=$TAICHI_REPO_DIR/bin/:$PATH

remove what?

[yuanming-hu]

Please remove all four env vars.

Share my experience here:
Environment: ubutnu16.04
Steps:

1. upgrade python3.5 to python3.7.
2. Download taichi_nightly-0.3.20-cp37-cp37m-manylinux1_x86_64.whl from https://pypi.org/project/taichi-nightly/#files
   (pip3 install can not install the latest version, so use this method)
3. pip3 install taichi_nightly-0.3.20-cp37-cp37m-manylinux1_x86_64.whl
4. python3 fractal.py

Seem that CXXABI's is not satisfied. So I give up Ubuntu. Using Mac.
Mac is so easy.
Just the command below is OK.
_python3 -m pip install taichi-nightly
python3 fractal.py_

Could you try run
print(__import__('taichi').__file__)?

[archibate]

Your fractal.py is too old to run on latest Taichi. AFAIK Taichi v1.0 already deprecated ti.var. Please download the latest fractal.py on github to replace it. 无法顺畅的大口呼吸，是活着的最好证明
