Hi @axiezai, what is the output of conda info?

axiezai commented 5 years ago

Can you please try removing the version spec on those packages in binder/environment.yml and see where you end up for each version (e.g. conda list xtensor)?

axiezai commented 5 years ago

The environment was built successfully with no version specs, here are the versions in the environment: xtensor 0.17.3 0 QuantStack xtensor-blas 0.13.1 blas_openblas_0 [blas_openblas] QuantStack scikit-learn 0.19.2 py36_blas_openblasha84fab4_201 [blas_openblas] conda-forge

I was able to open and run the lorenz notebook without a problem, I'm not sure exactly which notebook makes use of xtensor and scikit-learn, if you need me to test them out, please let me know.

And if you think these versions are adequate, I assume we can close this issue?

blink1073 commented 5 years ago

Does it work for you locally if you change the version specs to 0.13 and 0.19? If so, would you mind making a PR?

axiezai commented 5 years ago

I will give this a shot tomorrow after my traveling ends, will keep you updated. And yes, will make a PR if everything works!

blink1073 commented 5 years ago

Great, thanks!

axiezai commented 5 years ago

Changing the version specs to 0.13 and 0.19 respectively worked.

I created a PR. Let me know if everything looks good, I will leave closing the issue to you :) thank you for the help.
