Issues with 'conda env update'

Part 1 (2018)
1

Running on Paperspace.

My pip version is

pip 18.0 from /home/paperspace/anaconda3/envs/fastai/lib/python3.6/site-packages/pip (python 3.6)

When I run this command

conda env update

I get error messages and it doesn’t seem to complete the update. Does anybody know how to resolve this?

Here is the output

Same problem

I’m having the same issue. Can’t get started with a new paperspace machine.

4

+1 Same here.

5

Same problem here. I tried to install it on my Ubuntu 16.04 machine with conda 4.5.4 and pip 10.0.1

6

@dillon is this a paperspace problem? Could you please look in to it?

7

Does downgrading pip to version 10 help?

8

I’m running into the possibly related issue mentioned here.

I tried downgrading by running fastai$ pip install pip==10.0.1 but received the same error:

pip._vendor.pkg_resources.RequirementParseError: Invalid requirement, parse error at "'; extra '"

9

Getting the same error message as the original post even after downgrading to pip 10.0.0.

I decided to create another machine on paperspace. Things worked fine at first, but once I ran conda env update, I received the same error message posted here, and now I can’t even open jupyter notebook in that new machine

10

I have the same error. Can someone help?

11

if @dillon’s issue is the same as what’s going around the forums right now, then I think there’s a hacky fix – my guess is jupyter_contrib_nbextensions is causing problems.

Fix:

  1. comment out the 4 jupyter lines in environment.yml
  2. run conda env update
  3. manually install the packages that weren’t installed (mkl-random, cython, etc)
  4. manually install the 4 jupyter packages that you commented out.

From this thread. Originally crashed into this issue trying to get things working on salamander in this thread.

12

I am using windows 10 laptop and have the same issue. “pip install” has parse error. “conda install” looks ok. Yesterday I set up another machine and that was successful.

13

@Borz I just gave this a try and it didn’t work for me. Did you have to comment out the jupyter lines in environment-cpu.yml in addition to environment.yml?

14

Alright, got it working with @Borz’s tip! I had to comment out one extra line:

# - jupyter
# - jupyter_client
# - jupyter_console
# - jupyter_core
# - conda-forge::jupyter_contrib_nbextensions

I commented these lines out in both environment-cpu.yml and environment.yml; not sure if doing it in both made any difference.

15

Same problem

16

I’ve commented out those lines for now, so a git pull should fix it.

At this moment, the workaround is to comment out those lines. Is this correct?
Or specifying some older version e.g. 5.5.0?

This link is release notes of Jupyter.

im getting an error when trying to run update conda whith the ‘conda env update’ bash command in paperspace fastai core virtual machine (vm).
the error is

‘Using Anaconda API: https://api.anaconda.org
SpecNotFound: Can’t process without a name’

my conda version is 4.3.3
is anyone else having this issue?

19

I just solved this for anyone else having this problem.
I had to add an ‘environment name’ which you can find by typing ‘conda info --envs’. this will give you a list of the conda environments. to update the ‘fastai’ environment you need to enter ‘conda update -n fastai --all’.
