I'm trying to create a new conda enviornment with tensorflow (GPU), version 1.4.1 with the following command conda create -n parsim_1.4.1 python=3 tensorflow-gpu=1.4.1.
However, it prints a weird conflict:
$ conda create -n parsim_1.4.1 python=3 tensorflow-gpu=1.4.1
Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

What's wrong here? How can I fix it?
EDIT
Thanks to @merv's comment, I've tried with Mamba, and indeed it gave better error message (and much much faster). If anyone's interested, that's the command that successfully installed my required versions:
mamba create -n parsim python=3 "tensorflow-gpu=1.4" pillow opencv -c shuangnan -c anaconda
CodePudding user response：
Conda's error reporting isn't always helpful. Mamba is sometimes better, and in this particular case it gives:

Encountered problems while solving:
- nothing provides cudatoolkit 8.0.* needed by tensorflow-gpu-base-1.4.1-py27h01caf0a_0
Even here, that py27 in the build string is weird, but it at least directs us to cudatoolkit 8.0, which is no longer hosted in the main channel. Instead, you need to include the free channel. The following works for me:
$ CONDA_SUBDIR=linux-64 CONDA_CHANNEL_PRIORITY=flexible \
mamba create -n foo \
-c anaconda -c free \
python=3 tensorflow-gpu=1.4.1
