Hi, It turns out that I haven’t been able to use PyArrow 4.0.0 either in Conda environments or python venvs. PyArrow does install using pip. However this is what I get if I ever want to use it:
>>> import pyarrow as pa Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/karlkatzen/anaconda3/lib/python3.8/site-packages/pyarrow/__init__.py", line 63, in <module> import pyarrow.lib as _lib ImportError: dlopen(/Users/karlkatzen/anaconda3/lib/python3.8/site-packages/pyarrow/lib.cpython-38-darwin.so, 2): Symbol not found: __ZN5arrow10StopSource5tokenEv Referenced from: /Users/karlkatzen/anaconda3/lib/python3.8/site-packages/pyarrow/lib.cpython-38-darwin.so Expected in: /usr/local/lib/libarrow.400.dylib in /Users/karlkatzen/anaconda3/lib/python3.8/site-packages/pyarrow/lib.cpython-38-darwin.so >>> pa Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'pa' is not defined On the other hand a Conda installation is not even possible. Does anyone know what’s going on? Ying
