Whenever I try to update anything using conda, I get an error: ImportError: No module named tqdm. Here's the full traceback:

$ conda update conda

ImportError: No module named tqdm

However, when I try to install tqdm with pip, it says it is already installed:

$ pip install tqdm
Requirement already satisfied: tqdm in /usr/local/lib/python2.7/site-packages (4.32.2)

I am using Python 2.7 on MacOS Mojave with no virtual environments. How can I fix conda?

EDIT: I also tried: python -m pip install tqdm but it says requirement already satisfied.

Then I tried: /Users/user/anaconda2/bin/python -m pip install tqdm but it also says requirement already satisfied: Requirement already satisfied: tqdm in ./anaconda2/lib/python2.7/site-packages (4.31.1)

I ended up removing and reinstalling anaconda, which fixed the problem.

If you cannot use conda to install tqdm, something is seriously messed up.

In the best of cases, it's only about environment variables. Are you setting PYTHONPATH or similar? That could interfere with conda finding its own packages.

  1. Check your environment variables, don't set anything Python.
  2. Execute conda activate base.
  3. Check that python now is the one from the conda base environment.
  4. Call conda install.

In the worst of cases, you somehow uninstalled or broke a package that conda needs. In this case, re-install Miniconda from scratch in a different directory. You should use Miniconda3 (or Anaconda3) this time, as Python 2 is only half a year away from its end of life. Afaik, conda is able to mange existing environments from a previous installation, but I've never tried to use that feature.

If you haven't been using conda environments, but installed everything into the conda base environment, and that environment is messed up, I have no idea how to recover. You should always create custom conda environments for your projects.

for ubuntu 18.04

i faced the same issue on jupyter notebook, however the current apt install builds the 4.19 as latest which was bugged out for me.

Here are my steps for the solution:

Download the desired newer version http://old-releases.ubuntu.com/ubuntu/pool/universe/t/tqdm/

cd to deb file location

sudo dpkg -i <filename.deb>
