Can't install Tensorflow Mac
Update: version 1.13 introduces Python 3.7 support
The recent release candidate for the 1.13 version brings Python 3.7 support, in particular precompiled CPU wheels are also available for MacOS 10.11 and newer (link to 1.13.1). Install as usual:
$ pip install tensorflow>=1.13
Original answer (outdated)
tensorflow
does not support Python 3.7 at the moment. The reason for this is that:
tensorflow
usesasync
as function parameter name, andasync
andawait
became reserved keywords in Python 3.7 (as pointed by @phd in this comment) - this is why you're getting the import error;Python 3.7 changed the return type of
PyUnicode_AsUTF8AndSize
function in the C API used bytensorflow
:Changed in version 3.7: The return type is now
const char *
rather ofchar *
.
This means both issues must be fixed before tensorflow
can be built and released for Python 3.7 & Linux/MacOS. You can track the current status here: issue #20517.
The solution hence would be avoiding Python 3.7 if you need to continue working with tensorflow
. Stick with Python 3.6 for the time being.
If you are willing to build tensorflow
from source: There is a patch proposed to fix both issues. If you want to try it out, follow the Install TensorFlow from Sources tutorial from the official docs, the only difference being on the beginning:
Clone the repository
$ git clone https://github.com/tensorflow/tensorflow
Copy the patch contents to a file, e.g.
tf.patch
Apply the patch:
$ git apply tf.patch
Proceed with the rest of the tutorial.
Also note that you will have to build the latest protobuf
, as the support for Python 3.7 was added to it lately, but is not contained in any released version. Edit tensorflow/contrib/cmake/external/protobuf.cmake
to point to the current HEAD
of the protobuf
repo.
