Issue
I am trying to install pandas in to my conda environment using conda install pandas but the install fails because pandas has a dependency of pytz and pytz requires a minimum conda version of 4.3.
If I were running this on a normal Linux box I would just update my conda using 'conda update conda' and all would be sorted... However... the latest supported version of conda on a Rasperry Pi is 4.2.13 (using the rpi conda channel conda config --add channels rpi).
Help! Is it really not possible to use pandas in a conda environment on a Raspberry Pi 4B?!
To replicate the problem:
Raspberry Pi 4B, 8GB RAM with 64GB SD card)
OS: Raspbian Buster (10) (lsb_release -irdc)
IDE: Spyder 4
Python: 3.4.3 (python --version)
Virtual environment: Conda (Miniconda distribution)
Conda version: 4.2.13 (linux-armv7l) (conda info)
Current conda environment (conda list):
conda 4.2.13
conda-env 2.6.0
ncurses 6.1
openssl 1.0.1k
pip 20.1.1
psycosat 0.6.1
pycrpto 2.6.1
python 3.4.3
pyyaml 3.11
readline 7.0
requests 2.7.0
ruamel_yaml 0.11.14
setuptools 18.1
SQLite 3.24.0
wheel 0.34.2
xz 5.0.5
yaml 0.1.7
zlib 1.1.11

Solution
I ran in the exact same problem. The solution was to dump miniconda (python=3.4) and use virtualenv and pip (which uses the system version python 3.7). Then all goes well.
