Instructions to create PDSH conda environment fails

[dwelden]

Fetching package metadata .........
Solving package specifications: ....

UnsatisfiableError: The following specifications were found to be in conflict:

• numpy ==1.11
• python 3.5*
  Use "conda info " to see the dependencies for each package.

Thanks for the report. What operating system are you on?

[dwelden]

Windows 7 Enterprise 64-bit Service Pack 1 (Version 6.1.7601). Conda version 4.2.13.

[jakevdp]

Huh. It might be that numpy 1.11 builds are not available for Windows on conda. I'd suggest using numpy 1.10 instead.

[jakevdp]

If this continues to be an issue, I'd ask for help on the conda mailing list.

[jakevdp]

I changed the requirement to 1.11.1 – you might check if that works better. I don't have access to a Windows machine, so all I can do is take shots in the dark here...

If you come up with a good solution please let me know.

Fails under Linux Mint 18 32-bit (Ubuntu Xenial) with Conda v4.2.13 also. Different UnsatisfiableError this time though:

`dave@dave-VirtualBox ~ $ conda create -n PDSH python=3.5 --file PDSHrequirements.txt

UnsatisfiableError: The following specifications were found to be in conflict:

What if you try with --channel conda-forge?

[jakevdp]

I think the best fix might be to remove the requirements file entirely, and go back to just listing dependencies in the README. It's less convenient, but I'm not certain it's possible to fix this so that it will work perfectly for everyone on all platforms, architectures, and package managers.

[dwelden]

Oddly enough, mixed results: on my Windows 64 system, the PDSH environment is installing as I type. On the linux system, same error as before. If the Windows environment is operational when it completes, I will abandon the linux environment and proceed. Either way, I will post at least one more time with the results.

Thanks for your patient assistance.

UPDATE: Adding --channel conda-forge worked for Windows 64-bit environment creation, had no impact on linux 32-bit environment creation.
