plaidml-setup uses the wrong lib path and gets OSErrors

问题

I'm trying to install plaidml-keras on macOS High Sierra. I followed the instruction guide:

pip install -U plaidml-keras
plaidml-setup

Then I got the following errors:

Traceback (most recent call last):
  File "/Users/bogao/anaconda3/envs/plaidml/lib/python3.6/site-packages/plaidml/__init__.py", line 154, in load_library
    return ctypes.cdll.LoadLibrary(libpath)
  File "/Users/bogao/anaconda3/envs/plaidml/lib/python3.6/ctypes/__init__.py", line 426, in LoadLibrary
    return self._dlltype(name)

OSError: dlopen(/Users/bogao/anaconda3/envs/plaidml/lib/python3.6/site-packages/plaidml/libplaidml.dylib, 6): image not found

During handling of the above exception, another exception occurred:

The actual file is at /Users/bogao/anaconda3/envs/plaidml/lib/ And plaidml is looking at /Users/bogao/anaconda3/envs/plaidml/lib/python3.6/site-packages/plaidml/

I also tried to use python venv, and got the same errors. How could I get plaidml to use the correct path?

回答1:

I am currently getting the same error as the second one... (that occurred during handling the first)

I had also the first error, but it went away after running the following commands:

export PLAIDML_NATIVE_PATH=/Users/[username]/opt/anaconda3/envs/python/lib/libplaidml.dylib
export RUNFILES_DIR=/Users/[username]/opt/anaconda3/envs/python/share/plaidml

I am currently trying to figure out how to solve the second one. If someone has any ideas, here's link to GitHub issue that I created: https://github.com/plaidml/plaidml/issues/1027
