找不到满足要求的版本 tensorflow-gpu==1.7.0

Question

I'm trying to install tensorflow-gpu ver. 1.7.0 on a virtual environment using pip. My python version is 2.7.12, and my OS is Scientific Linux ver. 7.4 (Nitrogen). When I try the following

pip install tensorflow-gpu==1.7.0

I get the following errors:

ERROR: Could not find a version that satisfies the requirement tensorflow-gpu==1.7.0 (from versions: none)
ERROR: No matching distribution found for tensorflow-gpu==1.7.0

Help?

If

$ python2 -c "from pip._internal.pep425tags import get_supported; print(get_supported()[0])"

returns cp27-cp27m-manylinux2014_x86_64 , it means that your distro ships Python 2.7 compiled without wide unicode support. tensorflow supports only Python 2.7 compiled with wide unicode support (tag cp27-cp27mu-... ), is thus not installable with the default Python 2.7. Either switch to Python 3 (supports wide unicode by default), or compile Python 2.7 from source, passing the --enable-unicode=ucs4 to configure script.
